Plant Electronics Limited is considering producing three new computer boards on a daily basis. Each board will be produced from various combinations of plastic, copper and transistors. The amount of each resources required per unit, the unit profitability, and the availability of the resources are summarized in the following table: 

Chip model

Plastic Copper Transistors Profit per unit GH¢ 𝑋12 2 1 1 4 T7 1 2 1 1.5 V8 1 1 1 3 Daily availability 80 80 70  

(a) Formulate the linear programming problem to determine the production levels for three models X12, T7 and V8 that will maximize profit. (b) Use solver to find optimal solution and sensitivity report.            c) Management have asked you to determine the optimal solution. Write your answer in a form of a report to be submitted to the management.      

kofi and Ama, computer consultants, are considering embarking on a joint project that will involve development of relatively small commercial software package for personal computers. The program involves scientific calculations for a specialized portion of the engineering market.

Kofi and Ama have broken down the project into nine tasks and have estimated the time required for each task. The list of these tasks, the times required and the precedence relationships are given below

XYZ company is developing different commercial projects according to customers’ demands and requirements. The company deals with all types of projects i.e., from small to large in all capacity from simple to complex in nature. There are different software development lifecycles which are followed for the design and development of the project. Whenever company gets a project, they analyze the customers’ requirements and determine project size, project budget, software quality requirement, timeframes of project delivery etc. and then appropriate model is selected. Suppose company gets a project to develop android based software for daily sale and purchase transactions of an organization. Keeping in view the nature, type, size and complexity of the software (sale and purchase transaction system). Assume that you are a part of project team and given a responsibility to choose an appropriate model from Waterfall, Spiral or Incremental model. Which model will you select for the given project and why?
