The Austin, Texas plant of Computer Products produces disk units for personal and small business computers. Gerald Knox, the plant’s production planning director, is looking over next year’s sales forecast for these products and will be developing an aggregate capacity plan for the plant based on this forecast. The quarterly sales forecasts for the disk units are as follows:

1st Quarter

2nd Quarter

3rd Quarter

4th Quarter

1,980

1,800

2,340

1,980

Ample machine capacity exists to produce the forecast. Each disk unit takes an average of 20 labor-hours. In addition, you have collected the following information:

  1. Inventory holding or carrying cost is $100 per disk unit per quarter. The holding cost is based on the inventory at the end of each quarter.
  2. The plant works the same number of days in each quarter, 12 five-day weeks, 6 hours per day.
  3. Beginning inventory is zero disk units.
  4. In a backlog situation, the customer will wait for his order to be filled but will expect a price reduction each quarter he waits. The price reduction is $300 per disk for the first quarter the customer waits, $700 for the second quarter the customer waits, and $900 for the third quarter the customer waits. In filling orders, backlogged items will always be filled before current quarter items,
  5. The cost of hiring a worker is $800 while the cost of laying off a worker is $950.
  6. The straight time labor rate is $20 per hour for the first quarter and increases to $22 per hour starting in the third quarter.
  7. Overtime work is paid at time and a half (150%) of the straight time work.
  8. Outsourcing (contract work) is paid at the rate of $475 per disk unit for the labor and you provide the material
  9. Demand during the fourth quarter of the prior year was 1,980 units.
  10. Assume that workers hired in any quarter will not need any training to reach full production in that quarter.

Compare the following two sales and operations plans.

i) Computer Products is considering a modified “matching” demand planning model for meeting the disk production. The company will hire and layoff workers to match the demand requirements each quarter as long as the capacity of the resulting workforce does not exceed 2,250 units per quarter. If it cannot meet the demand in a quarter because of this restriction, it will outsource the shortage. Ignoring the material cost, what is the total cost to produce the disks for the year? All workers will be fully utilized each quarter, in other words, there is no under utilization.

ii) As an alternative, the company will maintain a workforce capable of producing the demand during the fourth quarter of last year. All workers will be fully utilized each quarter. If there are more workers in a quarter than are required to produce the demand for that quarter, the excess units will be held in inventory for the following quarter. If demand is greater in a quarter than can be produced by the available workforce using straight time, the excess units will be provided using overtime. What is the total cost of this option, excluding the material cost?

Bobcat Logistical Solutions (BLS) is a third-party logistics service provider (3PL) serving the Ohio market (Columbus, Cincinnati, and Cleveland) as a noncontract partner with a broker that serves food and beverage processors and distributors including direct relationships with large food and beverage shippers. BLS owns a fleet of trucks used to serve the “spot” markets. Spot markets are the final destinations for food and beverage deliveries to grocery stores, institutions with large food service operations (public and private school systems, colleges and universities, prisons, etc.), franchised and independent restaurants, and large entertainment venues. Large shippers use 3PLs in spot markets when they need extra capacity or when major weather events keep large truck capacities off the road. Brokers usually act as intermediaries to utilize their carrier networks (including BLS) so shippers can deliver product to market. The largest food and beverage shipper in the United States has been challenged with three severe winters in a row along with natural disasters (hurricanes, tornadoes, floods) unlike any consecutive three-year period before. As the economy has grown, carriers who were not building assets during the recession now suffer from capacity limitations. During these severe conditions of the last three years, the use of 3PLs exploded, doubling the truck movements handled across the United States as compared to nonpeak capacity requirements.

Bobcat Logistical Solutions has experienced steady growth over the last five years, averaging 10 percent revenue growth each year. BLS has also taken advantage of the recent increase in spot markets with significant market share gains within its strategic group of 3PLs. The growth funded strategic initiatives for BLS included adding trucks to the fleet, purchasing warehouse space in key locations, integrating innovative electronic logging devices into all vehicles ahead of government mandates, and establishing a stable driver pool by collaborating with a specialized veterans recruiting and placement firm.

The increased ownership in warehouse space has established an effective distribution center model that has differentiated Bobcat Logistical Solutions from other 3PLs and brokers in their capability to handle freight. Using state and local tax incentives, BLS has been a leader in improving sustainability by reducing fuel consumption, electric bills, and greenhouse gas emissions. BLS has been working with a local university on a software project to develop a proprietary warehouse management system (WMS) to improve operations of the 24/7 distribution center using RFID technology, and to improve carbon footprints to meet sustainability targets. The WMS has added value by providing data directing changes in four areas:

    1. Operating efficiencies with energy reduction gains—Inventory movement analysis displays opportunities to reduce energy costs by cycling conveyer belts off during idle times and managing lighting with sensors that switch off lights in empty rack areas.
    2. Partner with energy utilities—Data on energy use provide opportunities to work with local utility companies to purchase off-peak rates and make equipment scheduling adjustments.
    3. Picking route scheduling—Material movement scheduling can produce routes that are more efficient, save energy, and improve labor efficiencies. Efficient routing can reduce forklift usage in both numbers of forklifts needed and utilization of existing equipment, saving fuel costs, and reducing emissions. Well-organized picking routes in the warehouse eliminate unnecessary travel when using a WMS picking system rather than order-based picking (pick one order at a time).
    4. Reduce packaging costs—Information from the WMS can aid in reducing packaging materials by optimizing the size of the box and amount of packing materials, maximizing cube in trucks, and minimizing damage to goods.

While the increased utilization of 3PLs increased capacity to reach spot markets, the increased cost of adding broker fees and 3PL capacity has negatively influenced budgets for the large food shippers that Bobcat Logistical Solutions serves. The large food shippers across the country are resetting strategic initiatives as it relates to using Brokers and 3PLs. They need to reduce exposure to volatile spot markets, increase service consistency, more accurately forecast capacity, and reduce added or unbudgeted costs of using spot market brokers and 3PLs. Many large food and beverage shippers are setting new broker/3PL network targets with drastic cuts to the total number of brokers and 3PLs used. This initiative seeks to reign in the costs of added margins of brokers and 3PLs, geographic overlaps, and inconsistent service. A second approach for some shippers includes developing a stronger network with asset-based 3PL carriers. This initiative focuses on strategic partnerships with a smaller number of brokers who work with asset-based 3PLs or directly with the 3PLs. These partnerships are generally contract based so that volume will be optimized and product handling and capacity secured. The most desirable 3PL partners will be in important spot markets and be more technology-based providers. A third initiative for a few of the larger food and beverage shippers involves connecting with 3PLs who have been active in mergers or acquisitions of 3PLs in strategic geographic regions of the country. Partnering with these 3PLs provides many advantages: expanded scale of warehousing operations, broadened service offerings, expanded geographic coverage, more assets and/or technology, new management talent, new customers, more market share, greater knowledge in a targeted industry, and in some instances, reduced need for broker networks.

A large food and beverage manufacturer has approached BLS as part of their supply chain integration management effort. Midwest Food and Beverage Transportation (MFBT) is extending the process integration beyond their largest food and beverage shippers to second-tier supply chain partners and has targeted several 3PLs.

1. Identify and briefly explain the key items that Bobcat Logistical Solutions’ proposal should include to secure the 3PL contract with Midwest Food and Beverage Transportation’s supply chain integration efforts? (Hint: Consider the key supply chain business processes in Chapter 13)
