If you switch to the new machine, you anticipate that you can produce and sell 142,500 units at a beginning price of $9.50 per unit. WebIn this study unrelated parallel machine scheduling problem (UPMSP) with preventive maintenance (PM) and sequence dependent setup times (SDST) is investigated. A novel imperialist competitive algorithm (NICA) with multi-elite individuals guidance is proposed to minimize makespan and total tardiness simultaneously.
WebMay 1, 1993 · We consider the following parallel machine scheduling problem. Each of n independent jobs has to be scheduled on one of m unrelated parallel machines. The … Unrelated-machines scheduling is an optimization problem in computer science and operations research. It is a variant of optimal job scheduling. We need to schedule n jobs J1, J2, ..., Jn on m different machines, such that a certain objective function is optimized (usually, the makespan should be minimized). The time … See more Minimizing the maximum completion time (makespan) Minimizing the maximum completion time is NP-hard even for identical machines, by reduction from the partition problem. Horowitz and Sahni … See more There is a special case in which pi,j is either 1 or infinity. In other words, each job can be processed on a subset of allowed machines, and its run-time in each of these machines is 1. This variant is sometimes denoted by " P pj=1,Mj See more • Summary of parallel machine problems without preemtion See more A natural way to formulate the problem as a linear program is called the Lenstra–Shmoys–Tardos linear program (LST LP). For each machine i and job j, define a variable $${\displaystyle z_{i,j}}$$, which equals 1 iff machine i processes job j, and 0 otherwise. … See more Kim, Kim, Jang and Chen extend the problem by allowing each job to have a setup time, which depends on the job but not on the machine. They present a solution using See more
