Macon Controls produces three different types of control units used to protect industrial equipment from overheating. Each of these units must be processed by a
machine that Macon considers to be their process bottleneck. The plant operates on two 8-hour shifts, 5 days per week, 52 weeks per year. The table below provides the
time standards at the bottleneck, lot sizes, and demand forecasts for the three units. Because of demand uncertainties, the operations manager obtained three demand
forecasts (pessimistic, expected, and optimistic). The manager believes that a 25 percent capacity cushion is best.

- NTS is a Swiss intermodal operator located in Lausanne. When customers need to transport goods between origin and destination, NTS supplies them with one or more empty containers in which the goods can be loaded.Upon arrival at the destination, the goods are unloaded, and the empty containers must be transported to the pickup point for new customers. Therefore, NTS management needs to reallocate empty containers periodically (every week). The company's focus is on the transportation activity of empty containers, which is very expensive (almost 35% of the total operational costs). In May 2023, several empty containers, totaling 20 containers, need to be reallocated among terminals in Amsterdam, Berlin, Munich, Paris, Milan, Barcelona, and Madrid. The available or requested number of empty containers at various terminals is reported, along with the transportation costs (in euros per container) as seen in Figure 1.

These long cylindrical metal tanks contain various gases used in manufacturing cans of spray paint. The gas tanks are delivered to the warehouse by truck. Two receiving dockworkers unload the containers from the delivery trucks and place them on four wheel trucks. Two materials handlers are responsible for pushing the loaded trucks into the warehouse, unloading the tanks and setting them up on end. The two materials handlers spend a major portion of their day moving loads of the gas tanks into the warehouse and placing them into the proper storage locations. In total, there are five different types of gases that in equal proportion make up 98% of all gas handled. Question: Management would like to identify a better way to handle these gas tanks.

- R. C. Coleman distributes a variety of food products that are sold through grocery store and supermarket outlets. The company receives orders directly from the individual outlets, with a typical order requesting the delivery of several cases of anywhere from 20 to 50 different products. Under the company’s current warehouse operation, warehouse clerks dispatch order-picking personnel to fill each order and have the goods moved to the warehouse shipping area Because of the high labor costs and relatively low productivity of hand order picking, management has decided to automate the warehouse operation by installing a computer-controlled order-picking system along with a conveyor system for moving goods from storage to the warehouse shipping area. R. C. Coleman’s director of material management has been named the project manager in charge of the automated warehouse system. After consulting with members of the engineering staff and warehouse management personnel, the director compiled a…arrow_forwardA gold mining area in Lanao contains on average, 1 ounce of gold per ton.

- The Canadian government has built a large grain-shipping port at Churchill, Manitoba, on the Hudson Bay. Grain grown in southern Manitoba is carried by rail to Churchill during the open-water shipping season. Unfortunately the port is open only 50 days per year during July and August. This leads to some critical crew staffing decisions by management. The port has the capacity to load up to 7 ships simultaneously, provided that each loading bay has an assigned crew. The remote location and short shipping season results in a very high labor cost for each crew assigned, and management would like to minimize the number of crews. Ships arrive in a random pattern that can be modeled using the Poisson probability model. If a ship arrives and all available loading bays are filled, the ship will be delayed, resulting in a large cost that must be paid to the owner of the ship. This penalty was negotiated to encourage ship owners to send their ships to Churchill.Results of an initial analysis…arrow_forwardThe MidLands Trucking Company based in Louisvillehas eight trucks located throughout the Mideast that havedelivered their loads and are available for shipments.

With the existing brake lathe machine, the firm utilizes five employees who produce an average of eighty disc pads per hour; each of the employees receive $10 per hour; the machine cost is $40 per hour. The firm purchased a new brake lathe machine to replace the existing brake lathe machine; this reduced the labor content of the jobs needed to produce the disc pads. With the new brake lathe machine, the firm was able to shift one of the employees to another division; the machine cost increased by $10 per hour; and the production output increased by four disc pads per hour. Calculate the labor productivity (disc pads per employee per hour) with the existing brake lathe machine, and with the new brake lathe machine. Calculate the multi-factor productivity (disc pads per $) with the existing brake lathe machine, and with the new brake lathe machine.
