Chapter 12, Problem 3.2Q
Summary Introduction
To find:The average pipeline inventory for the two-train pull style system and the average size of stockpile of coal. Also, how small is the new stockpile than the stockpile of 150-railcar unit delivery system.
Introduction:The production system of every company or organization must ensure that an adequate flow of inventory is maintained. The flow of inventory is managed by reorder point systems where the inventory levels are monitored so that when the stock drops to a certain minimum point, said as reorder point, the next stock can be made ready. The goods are also secured in advance to meet the demands which are known as stockpiling.

Many terminals’ studies reported that a freight car spends an average of 62% per cent of its time in either terminal yards or intermediate yards, which is does not producing any revenue. The car spends only 14 per cent of its time in line haul operations and, of this, only 6.6 per cent in revenue producing service; from the theoretical background that you have, analyze the activities that consume most of the freight car time and assess the added value of these activities.
What are the problems that may appear in the following shelving system:
Narrow racking systems
Wide aisle racking systems
Movable racking systems
Drive racking systems
And how can these problems be solved?
Cakes baked by the Freshfood Bakery are transported fromthe ovens to be packaged by one of three wrappers. Eachwrapper can wrap an average of 120 cakes per hour (Poissondistributed). The cakes are brought to the wrappers at therate of 300 per hour (Poisson distributed). If a cake sitslonger than 5 minutes before being wrapped, it will not befresh enough to meet the bakery’s quality control standards.Does the bakery need to hire another wrapper?

- Cakes baked by the Freshfood Bakery are transported from the ovens to be packaged by one of three wrappers. Each wrapper can wrap an average of 200 cakes per hour. The cakes are brought to the wrappers at the rate of 500 per hour. If a cake sits longer than 5 minutes before being wrapped, it will not be fresh enough to meet the bakery’s quality control standards.

All four companies say that their normalservice time to deliver these shipments is two business days. The four carriers competewith each other on the basis of price and service quality rating, as shown in the following table. The price reported in the table is the (nondiscounted) cost per hundredweight(cwt) of sending a 600-pound shipment from Lexington to Springfield at freight class70. The service quality rating measures a carrier’s loss and damage record and goesfrom 0 (poor quality) to 100 (high quality). Which of these LTL carriers are on the efficient frontier?arrow_forwardThis effect is concerned with the firm being able to engage with the customer at the right place/time—its ability to do so 24/7 from any location.

- Evaluate an alternative that involves consolidating all 20-foot container volumes and using onlya single consolidation center in Shanghai/Ningbo. Assume that all the existing 20-foot containervolumes and the existing consolidation center volumes are sent to this single consolidationcenter by suppliers. This new consolidation center volume would be packed into 40-footcontainers, filled to 96 percent, and shipped to the United States. The existing 40-foot volumewould still be shipped direct from the suppliers at 85 percent capacity utilizationarrow_forwardThe sanitary landfill charges companies $200 per load and individuals $50 per load. On average, 90 companies tip their trucks each day at the landfill with a standard deviation of 30. There is time only for 110 deliveries in any combination of companies and individuals throughout the course of an eight-hour day. Company dump trucks enter through Gate A and individuals enter through Gate B. Individual demand is plentiful – often there are individuals turned away due to lack of capacity. It costs the landfill $30 to process a company dump truck and $15 to process an individual load. What is the expected profit for one day if the landfill allocates the optimal quantity of capacity to company trucks and individuals fill up the remainder of the сараcity? -arrow_forwardUsing revenue management, determine how many seats should be reserved for premium ticket holders.arrow_forward
- The Finishing Department had 5,000 incomplete units in its beginning Work-in-Process Inventory which were 100% complete as to materials and 30% complete as to conversion costs. 15,000 units were received from the previous department. The ending Work-in-Process Inventory consisted of 2,000 units which were 50% complete as to materials and 30% complete as to conversion costs. The Finishing Department uses first-in, first-out (FIFO) process costing.What are the equivalent units of production for the conversion costs during the period? 17,100. 14,500. 15,100. 16,500.arrow_forwardThe College Avenue Sub Shop is located in a small college town. Virtually all of its phone delivery orders are in the evening, between 5:00 P.M. and 1:00 A.M., so the shop has a delivery person for that time period. It receives an average of about 3 orders per hour (Poisson distributed). However, because of the different distances the delivery person must travel, the service time is undefined, with a mean of 15 minutes and a standard deviation of 6 minutes. Compute L, Lq, W, and Wq.arrow_forwardEvaluate an alternative that involves consolidating all 20-foot container volumes and using onlya single consolidation center in Shanghai/Ningbo.

- TSA security agents at the security gate at the Tri-Cities Regional Airport are able to check passengers and process them through the security gate at a rate of 50 per hour (Poisson distributed). Passengers arrive at the gate throughout the day at a rate of 40 per hour (Poisson distributed) the passenger traffic arriving at the airport security gate varies significantly during the day. At times close to flight takeoffs, the traffic is very heavy, while at other times there is little or no passenger traffic through the security gate. At the times leading up to flight takeoffs, passengers arrive at a rate of 110 per hour (Poisson distributed). Suggest a waiting line system that can accommodate this level of passenger traffic.arrow_forward601 Ana Chavarria, front office manager at The Times Hotel, has completed a revenue management semi- nar at Keystone University and is preparing an argu- ment in favor of adopting this concept at The Times Hotel to present to Margaret Chu, the general man- ager. She begins by compiling a history of room occupancy and ADRS, which she hopes will reveal areas in which revenue management could help. She prepares an electronic spreadsheet that lists rooms sold with corresponding room rates and correlates the data to tourism activities in the area. Ana sends an analysis of revenue realized and revenue potential to Ms. Chu for review prior to their discussion After reviewing the analysis, Ms. Chu concludes, "This is just another scam; the industry is slow to adopt this," and disregards the entire report. She knows that occupancy percentage, ADR, and RevPAR are all you need to be efficient today, so why change? Ana passes Ms. Chu in the lobby, and Ms. Chu indicates her distrust of the revenue…arrow_forwardAnalyzing Disaster Situations at Tech Two area hospitals have jointly initiated several planning projects to determine how effectively their emergency facilities can handle disaster-related situations at nearby Tech University. These disasters could be weather related (such as a tornado), a fire, accidents (such as a gas main explosion or a building collapse), or acts of terrorism. One of these projects has focused on the transport of disaster victims from the Tech campus to the two hospitals in the area, Montgomery Regional and Radford Memorial. When a disaster occurs at Tech, emergency vehicles are dispatched from Tech police, local EMT units, hospitals, and local county and city police departments. Victims are brought to a staging area near the disaster scene and wait for transport to one of the two area hospitals. Aspects of the project analysis include the waiting times victims might experience at the disaster scene for emergency vehicles to transport them to the hospital, and…arrow_forward
