Concept explainers
a)
To determine: number of hours operates for each mine so that contracted obligations can be met at low cost by formulating linear programming and solves it graphically.
Introduction: Linear programming is used to obtain the best possible outcome from the given real-world problem which is subjective to constraints and inequalities. It is used to make decisions based on business objectives. It is used in business planning, industrial engineering, and physical science. Express the real-world problem into the mathematical expression to get the optimal solution from the linear programming.
b)
To determine: number of hours operates for each mine so that contracted obligations can be met at low cost by formulating linear programming and solves it in excel.

- LAW ENFORCEMENT. The police department of the city of Flint, Michigan, has divided the city into 15 patrol sectors, such that the response time of a patrol unit (squad car) will be less than three minutes between any two points within the sector. Until recently, 15 units, one located in each sector, patrolled the streets of Flint from 7:00 P.M. to 3:00 A.M. However, severe budget cuts have forced the city to eliminate some patrols. The chief of police has mandated that each sector be covered by at least one unit located either within the sector or in an adjacent sector. The accompanying figure depicts the 15 patrol sectors of Flint, Michigan. Formulate and solve a binary model that will determine the minimum number of units required to implement the chief ’s policy.arrow_forwardThere are two companies manufacturing drones. Company A manufactures mass market drones, while company B manufactures customised drones according to customers’ requirements. In 2020, company A produces 3,200 drones, 3% of which were found to be defective and cannot pass the quality check. Company A employs 5 workers working an average of 8 hours a day in the drone production, and they worked 200 working days in 2020.In contrast, company B produces 900 drones, 10% of which were found to be defective and cannot pass the quality check. Company B employs 3 workers working an average of 6 hours a day in the drone production, and they worked 170 days in 2020. (a) If the drone manufacturing is seen as a process, what is considered as the output of the production processes of companies A and B and why?

(c) Is it reasonable to compare the manpower productivity of the two companies and reach a conclusion that one company…arrow_forwardManning Systems is a commercial software vendor that sells billing and other financial software to companies around the globe. Manning operates a centralized call center for customer support calls. Costs associated with use of the center are charged to the division with primary responsibility for the client. There are four geographical divisions: North America (NA), Central and South America (SA), Europe, and Asia-Pacific (APAC). The allocation is based on the length of time of calls made (Minutes). Idle time of the reservation agents and the fixed cost of the equipment are allocated based on the number of calls received (Calls) from clients in each division. Due to recent increased competition in the commercial software business, Manning has decided that it is necessary to better allocate its costs in order to price its services competitively and profitably. During the most recent period for which data are available, the use of the call center for each division was as follows:…arrow_forward
- Office Equipment, Inc. (OEI) leases automatic mailing machines to business customers in Fort Wayne, Indiana. The company built its success on a reputation of providing timely maintenance and repair service. Each OEI service contract states that a service technician will arrive at a customer’s business site within an average of 3 hours from the time that the customer notifies OEI of an equipment problem. Currently, OEI has 10 customers with service contracts. One service technician is responsible for handling all service calls. A statistical analysis of historical service records indicates that a customer requests a service call at an average rate of one call per 50 hours of operation. If the service technician is available when a customer calls for service, it takes the technician an average of 1 hour of travel time to reach the customer’s office and an average of 1.5 hours to complete the repair service. However, if the service technician is busy with another customer when a new…arrow_forwardThe maintenance department of an Oil and Gas Company has 6 large drilling equipment waiting for repairs.

- Star Garage Limited provides motor vehicle accessories and services for a wide range of vehicles in Dominica. Customers purchase parts to take to their individual mechanics to complete vehicle repairs or they may choose to bring their vehicles to Star Garage for in-house repairs and servicing. This means that they pay for both the parts and the labour associated with the type of service required. Some services do not include any new parts, just the labour costs for that service. Individual customers must pay for all parts purchases in full at the time of sale. Individual customers must pay 50% down when they bring their vehicles in for servicing and pay the balance when they come to pick them up when the job is completed. Corporate customers, however, are billed monthly for all sales (parts or service). Although Star Garage Limited has several different banking accounts, all sales are deposited intact into its main chequing account. Star Garage Limited purchases its inventory of parts…arrow_forwardDaniel works as a programmer for a large software company. He writes and tests utility programs such as compilers. His company operates two computing shifts: during the day for program development and online applications are running at night batch production jobs. Daniel has access to workload data and learns that the evening batch runs are complementary to daytime programming tasks; that is, adding programming work during the night shift would not adversely affect the performance of the computer to other users. Daniel comes back after normal hours to develop a program to manage his own stock portfolio. His drain on the system is minimal, and he uses very few expendable supplies, such as printer paper. Discuss the ethical principles that Daniel violated as an IT Professional.arrow_forwardA certain city the Transportation Authority (CTA) has trollies leaving regularly throughout the day beginning at 5:00 a.m. Although the length of a trip and the number of stops are constant, the time taken for each trip varies due to weather, traffiffiffic, and time of the day. According to the CTA, the mean time taken for the trip is 50 minutes. Suppose the travel time is Normally distributed with standard deviation σ = 4 minutes. A random sample of 25 trips is obtained, and the time for each is recorded. Find the probability that the sample mean time will be less than 48 minutes.arrow_forward
- The Cove is a midsized furniture store. Sales staff are assigned standard shifts (1st shift usually takes place between the hours of 9 a.m. and 5 p.m. 2nd shift is worked between 5 p.m. and 1 a.m. 3rd shift typically takes place between the hours of 12 a.m. and 8 a.m.), and the number of customers arriving per shift averages 40, Poisson distributed. A salesperson can deal with one customer in 5 minutes on average and costs the company $100 per shift in salaries and fringe benefits. Service times closely follow an exponential distribution. The manager is reviewing the number of salespersons to schedule for each shift. The cost of customers waiting before they receive service has been estimated at $2 per minute in terms of lost sales and loss of goodwill. a. If management wants to minimize the cost of both sales staff and customer wait times, how many salespersons should be working in each shift? b.
