- The manager of a regional warehouse must decide on the number of loading docks to request fora new facility in order to minimize the sum of dock costs and driver-truck costs. The manager haslearned that each driver-truck combination represents a cost of $300 per day and that each dockplus loading crew represents a cost of $1,100 per day.a. How many docks should be requested if trucks arrive at the rate of three per day, each dockcan handle five trucks per day, and both rates are Poisson?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.Determine how to solve the problem with the goal of minimizing…NTS is a Swiss intermodal operator located in Lausanne.

How many docks should be requested if trucks arrive at the rate of three per day, each dockcan handle five trucks per day, and both rates are Poisson?b. An employee has proposed adding new equipment that would speed up the loading rate to 6trucks per day. The equipment would cost $100 per day for each dock. Should the managerinvest in the new equipment?1) Rane Brake Lining produces disc pads for the automobile industry. 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. Calculate the productivity change (%) in labor productivity, and…On average, 100 customers arrive per hour at GothamCity Bank. It takes a teller an average of two minutesto serve a customer. Interarrival and service times areexponentially distributed. The bank currently has fourtellers working. The bank manager wants to compare thefollowing two systems with regard to the average numberof customers present in the bank and the probability that acustomer will spend more than eight minutes in line.■ System 1: Each teller has his or her own line (andno moving between lines is permitted). Arrivingcustomers are equally likely to choose any teller.■ System 2: All customers wait in a single line forthe first available teller.If you were the bank manager, which system wouldyou prefer?
- Chapter 5. (M/M/s/K Model). Leia is responsible for 12 computers in the IT offices in a small business called DataWish. Each computer runs on an average for 4 weeks and requires an average of ½ or 0.5 weeks to get reset by Leia before it can start up again. If we assign the Poisson distribution to the “arrival” of each computer for service and an exponential distribution to the actual service provided, answer the following questions: a. The arrival rate would be units per week and the service rate would be units per week. b. Calculate the following operating characteristics for the M/M/s/K system: Utilization Factor (ρ) % Performance Measures P0 (probability that sytem is empty) % L (average units in system) units Lq (average units waiting in queue) units W (average time in the system) weeks Wq (average time in the queue) weeks c. If we assign a cost of waiting as $750 per week per computer and $800 per week of…Problem 11-19 (Algorithmic) All airplane passengers at the Lake City Regional Airport must pass through a security screening area before proceeding to the boarding area. The airport has three screening stations available, and the facility manager must decide how many to have open at any particular time. The service rate for processing passengers at each screening station is 3 passengers per minute. On Monday morning the arrival rate is 5.2 passengers per minute. Assume that processing times at each screening station follow an exponential distribution and that arrivals follow a Poisson distribution. When the security level is raised to high, the service rate for processing passengers is reduced to 2 passengers per minute at each screening station. Suppose the security level is raised to high on Monday morning. Note: Use P0 values from Table 11.4 to answer the questions below. The facility manager's goal is to limit the average number of passengers waiting in line to 10 or fewer. How…Chapter 5. (M/M/s/K Model).

Two methods of processing are available; method A costs ₱1.5 M per ton and recovers 90% of gold; method B cost ₱1.3M per ton and recovers 80% of the gold. If gold can be sold for ₱2.4M per ounce, which method is better and by how much?Consider the Dynamic Program formulation of the n-class optimal booking problem with sequential arrivals.
