Exercise # 4 Lahore Engineering Works

Exercise # 4: Lahore Engineering Works (LEW) Lahore Engineering Works (LEW) is a manufacturer of heavy equipment and is considerin introducing a new line of small steamrollers. Development is to proceed as follows. First, a feasibility study will be performed. Upon receiving a successful feasibility report, manufacturing building is to be secured and a project leader hired. Once the building i secured, LEW will be committed to the project. Therefore an advertising group will b selected and the raw materials for the manufacturing process will be purchased. After th project leader has been hired, manufacturing staff will be recruited. After the manufacturing and advertising personnel are in place and the raw material purchased, a prototype model of the steamroller will be produced for the advertising stafft analyze After the prototype has been analyzed by the advertising staff, an advertisin campaign will begin. Following completion of the prototype, work will begin on a productio run of 10 steamrollers. The development phase of this project will be complete with the production of the first 10 steamrollers and the initiation of the advertising campaign. Two separate cost analyses have been prepared. One is effective under current condition: while the other is effective if the entire development phase is to be "crashed." These ar summarized below: Nomal Crash Task Description Time Cost Time Cost Weeks Weeks 1 Feasibility Study 6 80,000 5 100,000 Building Purchased 4 100,000 4 100,000 Project Leader Hired 3 50,000 100,000 Advertising Staff Selected 150,000 300,000 Materials Purchased 180,000 250,000 Manufacturing Staff Hired 10 300,000 7 480,000 Prototype Manufactured 100,000 2 100,000 First Production Run 450,000 5 800,000 Advertising Campaign 8 350,000 4 650,000 6 3 NWN 2 3 4 5 6 7 8 9 2 6 a) b) Under normal costs, find the earliest and latest start and finish times for each activity of the project. How long should the project take? How much would it cost? Which activities must not be delayed if the project is to be completed in the time calculated in part (a)? What is the shortest possible time that this project can finish? Suppose the prototype manufactured were delayed by four hours. By how muc time would the entire project be delayed? ch di) Exercise # 4: Lahore Engineering Works (LEW) Lahore Engineering Works (LEW) is a manufacturer of heavy equipment and is considerin introducing a new line of small steamrollers.
