Mid-South in Murfreesboro, Tennessee operates a high-energy plant providing precision heat treatments for high-speed tools – and also metal annealing and straightening services. This was a great business to be in before the energy crisis struck. That was about the same time the 2009 recession arrived. In no time at all the market was down 30%.
Investors had a pile of capital sunk into Mid-South?s three facilities spread across 21,000 square feet (2,000 square meters) of enclosed space. Within them, a number of twenty-five horsepower compressors plus a variety of electric, vacuum and atmospheric furnaces pumped out heat 27/7, 52 weeks a year. After the company called in the U.S. Department of Energy for assistance, several possibilities presented.
Insulate the Barium Chloride Salt Baths
The barium chloride salt baths used in the heat treatment process and operating at 1600?F (870?C) were a natural choice, since they could not be cooled below 1200?F (650?C) when out of use without hardening the barium chloride and clogging up the system. The amount of energy taken to prevent this came down considerably after they covered and insulated them. The recurring annual electricity saving was $53,000.
Manage Electrical Demand & Power
The utility delivers 480 volts of power to the three plants that between them consume between 825- and 875-kilowatt hours depending on the season. Prior to the energy crisis Mid-South Metallurgical regarded this level of consumption as a given. Following on the Department of Energy survey the company replaced the laminar flow burner tips with cyclonic burner ones, and implemented a number of other modifications to enhance thermal efficiency further. The overall natural gas reduction was 20%.
Implement Large Scale Site Lighting Upgrade
The 24/7 nature of the business makes lighting costs a significant factor. Prior to the energy upgrade this came from 44 older-type 400-watt metal halide fixtures. By replacing these with 88 x 8-foot (2.5 meter) fluorescent fittings Mid-South lowered maintenance and operating costs by 52%
The Mid-South Metallurgical Trophy Cabinet
These three improvements cut energy use by 22%, reduced peak electrical demand by 21% and brought total energy costs down 18%. Mid-South continues to monitor energy consumption at each strategic point, as it continues to seek out even greater energy efficiency in conjunction with its people.
For many people within the UK, water is not really something to worry about. Surely enough of it falls out the sky throughout the year that it does feel highly unlikely that we?ll ever run out of it. There certainly does seem to be an abundance of Branded Water available in plastic bottles on our supermarket shelves.
Water, water, every where, And all the boards did shrink; Water, water, every where, Nor any drop to drink.
Despite this, Once-unthinkable water crises are becoming commonplace. If you consider that In England and Wales, we use 16 billion litres of clean drinking water every day ? that’s equivalent to 6,400 Olympic sized swimming pools.
Currently, water companies can provide slightly more than we need ? 2 billion litres are available above and beyond what we’re using. In some areas, though, such as south east England, there is no surplus and, as such, these regions are more likely to face supply restrictions in a dry year.
If we take little moment to reflect on some of the most notable water related stories over the past few years, we’ll start to get a picture of just how real the potential and the threat of water shortages can be.
Reservoirs in Chennai, India?s sixth-largest city, are nearly dry right now. Last year, residents of Cape Town, South Africa narrowly avoided their own Day Zero water shut-off.
It was only year before that, Rome rationed water to conserve scarce resources.
Climate change is likely to mean higher temperatures which may drive up the demand for water (alongside population growth) and increase evaporation from reservoirs and water courses during spring and summer.
The impact of climate change on total rainfall is uncertain, but the rain that does fall is likely to arrive in heavier bursts in winter and summer. Heavier rain tends to flow off land more quickly into rivers and out to sea, rather than recharging groundwater aquifers.
A greater chance of prolonged dry periods is also conceivable. This combined with the harsh reality that no human population can sustain itself without sufficient access to fresh water.
If present conditions continue, 2 out of 3 people on Earth will live within a water-stressed zone by 2025
What is water stress?
Water stress is a term used to describe situation when demand for water is greater than the amount of water available at a certain period in time, and also when water is of poor quality and this restricts its usage. Water stress means deterioration in both the quantity of available water and the quality of available water due to factors affecting available water.
Water stress refers to the ability, or lack thereof, to meet human and ecological demand for water. Compared to scarcity, water stress is a more inclusive and broader concept.
Water Stress considers several physical aspects related to water resources, including water scarcity, but also water quality, environmental flows, and the accessibility of water.
Supply and Demand
Major factors involved when water scarcity strikes is when a growing populations demand for water exceeds the areas ability to service that need.
Increased food production and development programs also lead to increased demand for water, which ultimately leads to water stress.
Increased need for agricultural irrigation in order to produce more crops or sustain livestock are major contributors to localised water stress.
Overconsumption
The demand for water in a given population is fairly unpredictable. Primarily, based on the fact that you can never accurately predict human behaviour and changes in climate.
If too many people are consuming more water than they need because they mistakenly believe that water is freely available and plentiful, then water stress could eventually occur.
This is also linked to perceived economic prosperity of a give region. Manufacturing demand for water can have huge impact regardless whether water is actively used within the manufacturing process or not.
Water Quality
Water quality in any given area is never static. Water stress could happen as a result of rising pollution levels having a direct impact on water quality.
Water contamination happens when new industries either knowingly or unknowingly contaminate water with their industrial practices.
Largely, this can happen and frequently does so because these industries do not take effective control of monitoring and managing their impact on communal water supplies. Incorrectly assuming this is the responsibility of an additional third party like the regional water company.
The truth is, water quality and careful monitoring of it is all of our responsibility.
Water Scarcity
Simple increases in demand for water can in itself contribute to water scarcity. However, these are often preceded by other factors like poverty or just the natural scarcity of water in the area.
In many instances, the initial locations of towns or cities were not influenced by the close proximity of natural resources like water, but rather in pursuit of the extraction of other resources like Gold, Coal or Diamonds.
For Instance, Johannesburg, South Africa is the largest City in South Africa and is one of the 50 largest urban areas in the world. It is also located in the mineral rich Witwatersrand range of hills and is the centre of large-scale gold and diamond trade.
Johannesburg is also one of the only major cities of the world that was not built on a river or harbour. However, it does have streams that contribute to two of Southern Africas mightiest rivers – Limpopo and the Orange rivers. However, most of the springs from which many of these streams emanate are now covered in concrete!
Water Stress and Agriculture
Peter Buss, co-founder of Sentek Technology calls ground moisture a water bank and manufactures ground sensors to interrogate it. His hometown of Adelaide is in one of the driest states in Australia. This makes monitoring soil water even more critical, if agriculture is to continue. Sentek has been helping farmers deliver optimum amounts of water since 1992.
The analogy of a water bank is interesting. Agriculturists must ?bank? water for less-than-rainy days instead of squeezing the last drop. They need a stream of real-time data and utilize cloud-based storage and processing power to curate it.
Sentek?s technology can be found in remote places like Peru?s Atacamba desert and the mountains of Mongolia, where it supports sustainable floriculture, forestry, horticulture, pastures, row crops and viticulture through precise delivery of scarce water.
This relies on precision measurement using a variety of drill and drop probes with sensors fixed at 4? / 10cm increments along multiples of 12? / 30cm up to 4 times. These probe soil moisture, soil temperature and soil salinity, and are readily repositioned to other locations as crops rotate.
Peter Buss is convinced that measurement is a means to an end and only the beginning. ?Too often, growers start watering when plants don’t really need it, wasting water, energy, and labour. By accurately monitoring water can be saved until when the plant really needs it.
Peter also emphasises that crop is the ultimate sensor, and that ?we should ask the plant what it needs?.
This takes the debate a stage further. Water wise farmers should plant water-wise crops, not try to close the stable door after the horse has bolted and dry years return.
The South Australia government thinks the answer also lies in correct farm dam management. It wants farmers to build ones that allow sufficient water to bypass in order to sustain the natural environment too.
There is more to water management than squeezing the last drop. Soil moisture goes beyond measuring for profit. It is about farming sustainably using data from sensors to guide us.
Ecovaro is ahead of the curve as we explore imaginative ways to exploit the data these provide for the common good of all.
A Quarter of the World?s Population, Face High Water Stress
Data from WRI?s Aqueduct tools reveal that 17 countries? home to one-quarter of the world?s population?face ?extremely high? levels of baseline water stress, where irrigated agriculture, industries and municipalities withdraw more than 80% of their available supply on average every year.
Water stress poses serious threats to human lives, livelihoods and business stability. It’s poised to worsen unless countries act: Population growth, socioeconomic development and urbanization are increasing water demands, while climate change can make precipitation and demand more variable.
How to manage water stress
Water stress is just one dimension of water security. However, like any challenge, its outlook depends on adequate monitoring and management of environmental data.
Even countries with relatively high water stress have effectively secured their water supplies through proper management by leveraging the knowledge they have garnered by learning from the data they gathered.
3 ways to help reduce water stress
In any geography, water stress can be reduced by measures ranging from common sense to innovative technology solutions.
There are countless solutions, but here are three of the most straightforward:
1. Increase agricultural efficiency: The world needs to make every drop of water go further in its food systems. Farmers can use seeds that require less water and improve their irrigation techniques by using precision watering rather than flooding their fields.
Businesses need to increase investments to improve water productivity, while engineers develop technologies that improve efficiency in agriculture.
2. Invest in grey and green infrastructure: D Data produced by Aqueduct Alliance – shows that water stress can vary tremendously over the year. WRI and the World Bank?s researchshows that built infrastructure (like pipes and treatment plants) and green infrastructure (like wetlands and healthy watersheds) can work in tandem to tackle issues of both water supply and water quality.
3. Treat, reuse and recycle: We need to stop thinking of wastewater as waste.
Treating and reusing it creates a ?new? water source.
There are also useful resources in wastewater that can be harvested to help lower water treatment costs. For example, plants in Xiangyang, China and Washington, D.C. reuse or sell the energy- and nutrient-rich byproducts captured during wastewater treatment.
Summary
The data is undeniably clear, there are very worrying trends in water.
Businesses and other other organisations need to start taking action now and investing in better monitoring and management, we can solve water issues for the good of people, economies and the planet. We collectively cannot kick this can down the road any further, or assume that this problem will be solved by others.
It is time, for a collective sense of responsibility and for everyone to invest in future prosperity of our Planet as a collective whole. Ecological preservation should be at the forefront of all business plans because at the end of the day profit is meaningless without an environment to enjoy it in!
Hadoop is a data system so big it is like a virtual jumbo where your PC is a flea. One of the developers named it after his kid?s toy elephant so there is no complicated acronym to stumble over. The system is actually conceptually simple. It has loads of storage capacity and an unusual way of processing data. It does not wait for big files to report in to its software. Instead, it takes the processing system to the data.
The next question is what to do with Hadoop. Perhaps the question would be better expressed as, what can we do with a wonderful opportunity that we could not do before. Certainly, Hadoop is not for storing videos when your laptop starts complaining. The interfaces are clumsy and Hadoop belongs in the realm of large organisations that have the money. Here are two examples to illustrate the point.
Hadoop in Healthcare
In the U.S., healthcare generates more than 150 gigabytes of data annually. Within this data there are important clues that online training provider DeZyre believes could lead to these solutions:
Personalised cancer treatments that relate to how individual genomes cause the disease to mutate uniquely
Intelligent online analysis of life signs (blood pressure, heart beat, breathing) in remote children?s hospitals treating multiple victims of catastrophes
Mining of patient information from health records, financial status and payroll data to understand how these variables impact on patient health
Understanding trends in healthcare claims to empower hospitals and health insurers to increase their competitive advantages.
New ways to prevent health insurance fraud by correlating it with claims histories, attorney costs and call centre notes.
Hadoop in Retail
The retail industry also generates a vast amount of data, due to consumer volumes and multiple touch points in the delivery funnel. Skillspeed business trainers report the following emerging trends:
Tracing individual consumers along the marketing trail to determine individual patterns for different demographics and understand consumers better.
Obtaining access to aggregated consumer feedback regarding advertising campaigns, product launches, competitor tactics and so on.
Staying with individual consumers as they move through retail outlets and personalising their experience by delivering contextual messages.
Understanding the routes that virtual shoppers follow, and adding handy popups with useful hints and tips to encourage them on.
Detecting trends in consumer preferences in order to forecast next season sales and stock up or down accordingly.
Where to From Here?
Big data mining is akin to deep space research in that we are exploring fresh frontiers and discovering new worlds of information. The future is as broad as our imagination.?
The Japanese word Heijunka, pronounced hi-JUNE-kuh means ?levelling? in the sense of balancing workflows. It helps lean organizations shift priorities in the face of fluctuating customer demand. The goal is to have the entire operation working at the same pace throughout, by continuously adjusting the balance between predictability, flexibility, and stability to level out demand.
Henry Ford turned the American motor manufacturing industry upside down by mass-producing his iconic black motor cars on two separate production lines. In this photograph, body shells manufactured upstairs come down a ramp and drop onto a procession of cars almost ready to roll in 1913.
Smoothing Production in the Call Centre Industry
Call Centres work best in small teams, each with a supervisor to take over complex conversations. In the past, these tended to operate in silos with each group in semi-isolation representing a different set of clients. Calls came through to operators the instant the previous ones concluded. By the law of averages, inevitably one had more workload than the rest at a particular point in time as per this example.
Modern telecoms technology makes it possible to switch incoming lines to different call centre teams, provided these are multi-skilled. A central operator controls this manually by observing imbalanced workflows on a visual system called a Heijunka Box. The following example comes from a different industry, and highlights how eight teams share uneven demand for six products.
This departure from building handmade automobiles allowed Henry to move his workforce around to eliminate bottlenecks. For example, if rolls of seat leather arrived late he could send extra hands upstairs to speed up the work there, while simultaneously slowing chassis production. Ford had the further advantage of a virtual monopoly in the affordable car market. He made his cars at the rate that suited him best, with waiting lists extending for months.
A Modern, More Flexible Approach
Forces of open competition and the Six Sigma drive for as-close-to-zero defects dictates a more flexible approach, as embodied in this image published by the Six Sigma organisation. This represents an ideal state. In reality, one force usually has greater influence, for example decreasing stability enforces a more flexible approach.
Years ago, Japanese car manufacturer Toyota moved away from batching in favour of a more customer-centric approach, whereby buyers could customise orders from options held in stock for different variations of the same basic model. The most effective approach lies somewhere between Henry Ford?s inflexibility and Toyota?s openness, subject to the circumstances at the moment.
A Worked Factory Example
The following diagram suggests a practical Heijunka application in a factory producing three colours of identical hats. There are two machines for each option, one or both of which may be running. In the event of a large order for say blue hats, the company has the option of shifting some blue raw material to the red and green lines so to have the entire operation working at a similar rate.
Predictability, Flexibility, and Stability at Call Centre Service
The rate of incoming calls is a moving average characterised by spikes in demand. Since the caller has no knowledge whether high activity advisories are genuine, it is important to service them as quickly as possible. Lean process engineering provides technology to facilitate flexibility. Depending on individual circumstances, each call centre may have its own definition of what constitutes an acceptably stable situation.
