Management of High Tech Services (HTS) would like to develop a model that will help al- locate their technicians' time between service calls to regular contract customers and new customers. A maximum of 80 hours of fechnician time is available over the two-week plan- ning period. To satisfy cash flow requirements, at least $800 in revenue (per technician) must be generated during the two-week period. Technician time for regular customers generates $25 per hour. However, technician time for new customers only generates an average of $8 per hour because in many cases a new customer contact does not provide billable services. To ensure that new customer contacts are being maintained, the technician time spent on new customer contacts must be at least 60% of the time spent on regular customer contacts. Given these revenue and policy requirements, HTS would like to determine how to allocate techni- cian time between regular customers and new customers so that the total number of customers contacted during the two-week period will be maximized. Technicians require an average of 50 minutes for each regular customer contact and 1 hour for each new customer contact.

Southland Corporation's decision to produce a new line of recreational products resulted in the need to construct either a small plant or a large plant. The best selection of plant size depends on how the marketplace reacts to the new product line. To conduct an analysis, marketing management has decided to view the possible long run-demand as low, medium or high. The following table shows the projected profit in millions of dollars: Plant Size Low Medium High Small 150 200 200 Large 50 200 500 a. What is the decision to be made, and what is the chance event for Southland's problem? b. Construct a decision tree. c. Recommend a decision based on use of the optimistic, conservative, and minimax regret approaches.
Last year the Diamond Manufacturing Company purchased over $10 million worth of of- fice equipment under its “special ordering” system, with individual orders ranging from $5,000 to $30,000. Special orders are for low-volume items that have been included in a department manager’s budget. The budget, which limits the types and dollar amounts of office equipment a department head can requisition, is approved at the beginning of the year by the board of directors. The special ordering system functions as follows. c. Describe how the control procedures you recommended in part b should be modified if Diamond reengineered its expenditure cycle activities to make maximum use of current IT (e.g., EDI, EFT, bar-code scanning, and electronic forms in place of paper documents).d. Draw a BPMN diagram that depicts Diamond’s reengineered expenditure cycle.
Build-Right is a company offering house building and property improvement services to the public. The proprietor of the company employs a number of skilled workers such as bricklayers, carpenters and plumbers. The proprietor manages the building projects himself, and occasionally helps with the construction work. Build-Right wants to computerise the management of building work. This includes processing of cost estimates, job scheduling, and payments as described below. · When a customer contacts the company to ask for an estimate, the proprietor makes a note of the customer’s contact details and records an outline of the proposed work. He agrees a date with the customer to view the property in order to give an estimate of the cost for the work. Draw a levl 0 data flow diagram
PSSM: CaseProfessional and Scientific Staff Management (PSSM) is a unique type of temporary staffingagency. Many organizations today hire highly skilled technical employees on a short-term,temporary basis to assist with special projects or to provide a needed technical skill. PSSMnegotiates contracts with its client companies in which it agrees to provide temporary staff inspecific job categories for a specified cost. For example, PSSM has a contract with an oil and gasexploration company in which it agrees to supply geologists with at least a master's degree for$5,000 per week. PSSM has contracts with a wide range of companies and can place almost anytype of professional or scientific staff members, from computer programmers to geologists toastrophysicists.When a PSSM client company determines that it will need a temporary professional or scientificemployee, it issues a staffing request against the contract it had previously negotiated with PSSM.When PSSM's contract manager receives…
I WANT THE SOLUTION FOR NUMBER 6,7 AND 8 Let us consider an IT project P scheduled for 6 months where: Project team must develop two activities a month for 6 months • Each activity is planned to cost 50 $ • We observe the project at the beginning of month 5 and we find that 10 activities are already finished, and that CPI is equal to 0.4. 1. How is the project performing from a schedule perspective? 2. How is the project performing from a cost perspective? 3. What is the actual cost of the project? 4. If we assume that the COST variance experienced in the project will continue, how much more money will it take to complete the project? 5. If we suppose that the variance experienced were to stop, what is the project's estimate at completion? 6. What is the project's TCPI using the project's budget at completion? 7. If the project manager focuses on the percentage of the project that is complete. What should he/she report? 8. Imagine that…

Every company is expected to reduce and or eliminate the number of accidents that occur on theirpremises every year. Reduced the number of accidents on site will help manage the company’scompensation budget. If an employee is injured at work, the employer may be held liable for the injuryand they may end up paying a huge amount of money as compensation to the injured employee.A company in Wynberg recruits graduate trainees every year. The company has different rooms thatthe IT graduate trainees can use as labs for assembling and disassembling computers.To avoid clutter in the maintenance labs, all computer equipment is kept in the storeroom. Dependingon the practical for the week, the graduate trainees have to request the equipment that they require,from the technician. They then go and pick up the necessary equipment from the storeroom and signfor it.The safety of all members of staff is of paramount importance to the company.

A company specializing in custom-engineered equipment is planning to submit a proposal to the National 5. Aeronautics and Space Administration (NASA) to build an assembled component for a new space station that NASA plans to launch into orbit. The winning proposal will be selected on the basis of both cost and timely delivery. Also, there will be a penalty clause in the NASA contract for late delivery. The company has developed the schedule of activities that are required to produce the assembled component. The activities and precedence requirements are presented in the table below. Three time estimates (in weeks) are given for each activity: optimistic time, most likely time, and pessimistic time.

Test C. Great Corporations's decision to produce a new line of recreational products resulted in the need to construct either a small plant or large plant. The best selection of plant size depends on how the marketplace reacts to the new product line. To conduct an analysis, marketing management has decid3d to view the possible long-run demand as low, medium and high. Under low long-run demand, small plant size has payoff of P150 and large plant size has P50 payoff. Small plant size has payoffs of P200 in medium long-run demand. While large plant size has equal payoff with small size plant in case of medium long-run demand, large plant size projects a payoff P300 higher than that of the small plant size. 1. Construct the payoff table. 2. What is the decision to be made? 3. What is the chance event for the corporation's problem? 4. Construct a decision tree. 5. Recommend a decision based on the use of the optimistic, conservative and minimax regret approaches.
