Introduction:
HC, the manager of the branch office of state department motor vechiles at city M, analyzed the driver’s license-renewal operations which involved accomplishment of several tasks which is shown in the table below.
HC found that the operations were perfomed by different clerks and in the same sequence. He found that the office can process 120 applications per hour. He also discovered that the works were unevenly distributed where checking applications for violations demanded more time and the clerks took shortcuts to match up their speed with other operations.
The manager also found that steps 1 to 4, the clerks were paid $12 per hour and step 5 was performed by photographer who was paid $16 per hour and the last step of performed by state for issuing temporary liscence which cost $18 per hour. The review showed that step 1 and step 6 cannot be changed and has to be performed in the same order. He was under high pressure to increase productivity and reduce cost. The data collected by HC was,
To suggest: A process to accommodate 120 applications per hour and determine the cost of new configuration.

One of Jensen's regular customers asked him to prepare an estimate for the restoration of a 1964 model 356SC Porsche. To estimate the time and cost to perform such a restoration, Jensen broke the restoration process into four separate activities: disassembly and initial preparation work (A), body restoration (B), engine restoration (C), and final assembly (D). Once activity A has been completed, activities B and C can be performed independently of each other; however, activity D can be started only if both activities B and C have been completed. Based on his inspection of the car, Jensen believes that the following time estimates (in days) are applicable: Activity Optimistic Most Probable Pessimistic A 3 4 8 B 3 4 5 C 5 7 9 D 4 5 12 Jensen estimates that the parts needed to restore the body will cost $4000…arrow_forward

Because of the high labour costs and relatively low productivity of hand order-picking, management has decided to automate the warehouse operation by installing a computer-controlled order system, along with a conveyor system for moving goods from storage to the warehouse shipping area. ZY’s director of material management has been named the project manager in charge of automated warehouse system. After consulting with members of the engineering staff and warehouse management personnel, the director compiled a list of activities associated with the project. The optimistic, most likely, and pessimistic times (in weeks) have also been provided for each activity, as shown below.

He has been appointed as the department manager for an upcoming large chemical process plant that will be designed and constructed by the organization that he is currently attached to. Baha's responsibilities will include organizing the process unit staff and overseeing the project designers' sketch plans to ensure that the new plant will be designed safely, operable and maintainable. After the construction, he will then be responsible to start up the plant. From experience, Baha noted that a new type of valve sold by a newer supplier could be used in place of more common gate valves sold by established suppliers. In any case, the new valve was less expensive and often gave a tighter shut-off than the current gate valve used by his organization. Thus, Baha convinced the project designers to add more of these new valves to the design of the process unit. His decision improved safety because more flows could be shut off instantaneously in an…arrow_forward1. The activities involved in the construction of a certain project are given in Table 1.
