How Mid-South Metallurgical cut Energy Use by 22%

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.

Matrix Management: Benefits and Pitfalls

Matrix management brings together managers and employees from different departments to collaborate with each other towards the accomplishment of the organizational goals. As much as it is beneficial, matrix management also has limitations. Hence, companies should understand its benefits and pitfalls before implementing this management technique.

Benefits

The following are some of the advantages of matrix management:

Effective Communication of Information

Because of the hybrid nature of the matrix structure, it enables different departments to closely work together and communicate frequently in order to solve project issues. This leads to a proficient information exchange among leaders and subordinates. Consequently, it results to developed strategies, enhanced performance and quick productivity.

Efficient Use of Resources

Resources can be used efficiently in the organisation since it can be shared among functions and projects. As the communication line is more open, the valuable knowledge and highly skilled resources are easily distributed within the organisation.

Increased Motivation

The matrix structure promotes democracy. And with the employees working on a team, they are motivated to perform their duties better. The opinions and expertise of the employees are brought to the table and considered by the managers before they make decisions. This leads to employee satisfaction, empowerment and improved performance.

Flexibility

Since the employees communicate with each other more frequently, decision making becomes speedy and response is adaptive. They can easily adjust with diverse situations that the company encounters.

Skills Development

Matrix employees are pooled out for work assignments, even to projects that are not necessarily in line with their skill background. With this approach to management, employees have the chance to widen their skills and expertise.

Discipline Retention

One significant advantage of matrix management is that it enables the employees to maintain their skills in functional areas while working with multidisciplinary projects. Once the project is completed and the team wraps up, the members remain sharp in their discipline technically and return to their home functions.

Pitfalls

Here are some disadvantages of matrix management:

Power Struggle

In the matrix structure, there is always tension between the functional and project manager. Although their intent is polite, their conflicting demands and competition for control over the same resources make it more difficult.

Internal Complexity

Having more than one manager, the employees might become confused to who their immediate leader is. The dual authority can lead to internal complexity and possible communication problems. Worst, employee dissatisfaction and high employee turnover.

Heightened Conflict

In any given situation where people and resources are shared across projects, there would always be competition and conflict. When these issues are prolonged, conflicts will heightened and will lead to more internal problems.

Increased Stress

For the employees, being part of a matrix structure can be stressful. Their commitment is divided among the projects and their relationship with multiple managers requires various adjustments. Increased stress can negatively affect their performance in the long run.

Excessive Overhead Expenses

Overhead administrative costs, such as salaries, increase in a matrix structure. More expenses, more burden to the organisation. This is a challenge to matrix management that leaders should consider carefully.

These are just some of the advantages and disadvantages of matrix management. The list could go on, depending on the unique circumstances that organisations have. The key is that when you decide to implement matrix management, you should recognise how to take full advantage of its benefits and understand how to lessen, if not eradicate, the pitfalls of this approach to management.

What Energy Management Software did for CDC

Chrome Deposit Corporation ? that’s CDC for short ? reconditions giant rollers used to finish steel and aluminium sheets in Portage, Indiana by applying grinding, texturing and plating methods. While management was initially surprised when the University of Delaware singled their plant out for energy assessment, this took them on a journey to bring energy consumption down despite being in an expansion phase.

Metal finishing and refinishing is an energy-intensive business where machines mainly do the work while workforces as small as 50 individuals tend them. Environmental impacts also need countering within a challenging environment of burgeoning natural gas and electricity prices.

The Consultant’s Recommendations

The University of Delaware was fortunate that Chrome Deposit Corporation had consistently measured its energy consumption since inception in 1986. This enabled it to pinpoint six strategies as having potential for technological and process improvements.

  • Insulate condensate tanks and pipes
  • Analyse flue gas air-fuel ratios
  • Lower compressed air pressures
  • Install stack dampers on boilers
  • Replace belts with pulleys and cogs
  • Fit covers on plant exhaust fans

CDC implemented only four of the six recommendations. This was because the boiler manufacturer did not recommend stack dampers, and the company was unable to afford certain process automation and controls.

Natural Gas Savings

The project team began by analysing stack gases from boilers used to heat chrome tanks and evaporate wastewater. They found the boilers were burning rich and that several joints in gas lines were leaking. Correcting these issues achieved an instant gas saving of 12% despite increased production.

Reduced Water Consumption

The team established that city water was used to cool the rectifiers. It reduced this by an astonishing 85% by implementing a closed-loop system and adding two chillers. This also helped the water company spend less on chemicals, and energy to drive pumps, purifiers and fans.

Summary of Benefits

Electricity consumption reduced by 18% in real terms, and natural gas by 35%. When these two savings are merged they represent an overall 25% energy saving. These benefits were implemented across the company?s six other plants, resulting in benefits CDC management never dreamed of when the University of Delaware approached them.

Spreadsheet Fraud

To any company executive or business owner, the mere possibility of fraud can be enough to send alarm bells ringing – for good reason. In a prolonged recession, the last thing investors would want to discover is a huge, gaping hole where supposedly a neat profit should have been. Also to find out that such loss was brought about by deliberately falsified accounting and poor spreadsheet controls only makes the situation even more regrettable.

Why?

Because these losses would not have occurred had there been a stronger risk management program in place and more stringent quality control on critical data to begin with.

But given the nature of a spreadsheet system i.e. its sheer flexibility and easy accessibility, plus the fact that they were never intended to be enterprise-level tools, there are no hard and fast rules for auditing spreadsheets. Also because of the lack of internal controls for end user computing (EUC) applications, in this case spreadsheets, you can’t expect these systems to yield consistently accurate results.

In fact, most managers assume that major spreadsheet errors should result in figures that are blatantly out of touch with how things stand in the real world, making these errors easily detectable.

Well they assumed wrong. You’ll find cases where the losses ran to millions of dollars without anyone being the wiser.

In instances of fraud, the problem becomes more complicated as these errors are deliberately hidden and cleverly disguised, perhaps one erroneous cell at a time. Even if these cover-ups started out with smaller figures that may have had negligible impact on a company?s operation, the cumulative costs of these ?insignificant? errors multiply exponentially as the spreadsheets are reused and utilised as bases for other related reports.

While there is no generally accepted definition of the term ?spreadsheet fraud?, its quite easy to identify one when a case crops up. Fraud arising from spreadsheets are typically characterised by:

Fallacious inputs – correct figures are deliberately replaced with false values.

Erroneous outputs owing to data alteration – hyperlinks are linking to the wrong spreadsheets or cells; use of macros or special lines of code which are understandable only to the person who developed the code.

Concealment of critical information – can be done with easy ?tweaks? such as hidden rows and columns, using the same colour for both the font and the background, or hard coding additional values into a cell.

There is nothing really highly-sophisticated or technical in any of these methodologies. But without internal spreadsheet controls in place, it would take a discerning eye and a thorough review to catch the inconsistencies contained in a spreadsheet fraught with errors. Also, if these errors are knowingly placed there, the chances of finding them are close to nil.
