McDonalds follows a Just in Time (JIT) system of inventory management. The disadvantages of manufacturing technology include the following: Limited Creativity - Manufacturing technology completely limits creativity due to the abundance of automation/machinery and lack of employees within the production facility. This is a non-preemptive, pre-emptive scheduling algorithm. Found inside – Page 7-17A commonly accepted advantage of the dispatching approach is its simplicity and low cost , due to both the absence of a complete preliminary programming and system ... The job with the shortest processing time is processed first . As illustrated above, for the same set of jobs, SRT algorithm is faster in execution than SJN algorithm. Here, the task is divided into subparts and these subparts are then distributed among the available processors in the system. In the image below, job #6 has the shortest remaining processing time of thirty minutes, and hence would go first. P3. Example: In the above example, at time 1ms, there are two processes i.e. 1. The short processing time decreases the adverse effects of heating on the quality characteristics. Like the shortest processing time (SPT) rule, the earliest due date (EDD) rule minimizes the average flow time, The shortest processing time (SPT) rule and the earliest due date (EDD) rule will always provide the same sequence. The process which has the least processing time remaining is executed first. Shortest Processing Time Another method of job sequencing based on job completion time, the shortest processing time method assigns jobs with the shortest processing time first. Found inside – Page 5-36The following are advantages of the single-line configuration: 1. The arrangement guarantees “fairness” by ensuring that a ...
