WebScheduling is the process of arranging, controlling and optimizing work and workloads in a production process or manufacturing process. Scheduling is used to allocate plant and machinery resources, plan human resources , … The name originally came from the scheduling of jobs in a job shop, but the theme has wide applications beyond that type of instance. This problem is one of the best known combinatorial optimization problems, and was the first problem for which competitive analysis was presented, by Graham in 1966. [1] Meer weergeven Job-shop scheduling, the job-shop problem (JSP) or job-shop scheduling problem (JSSP) is an optimization problem in computer science and operations research. It is a variant of optimal job scheduling. … Meer weergeven Since the traveling salesman problem is NP-hard, the job-shop problem with sequence-dependent setup is clearly also NP-hard since the TSP is a special case of the JSP with a single job (the cities are the machines and the salesman is the job). Meer weergeven One of the first problems that must be dealt with in the JSP is that many proposed solutions have infinite cost: i.e., there exists $${\displaystyle x_{\infty }\in {\mathcal {X}}}$$ such that $${\displaystyle C(x_{\infty })=+\infty }$$. In fact, it is quite simple to … Meer weergeven Many variations of the problem exist, including the following: • Machines can have duplicates (flexible job shop with duplicate machines) or belong to groups of identical machines (flexible job shop). • Machines can require a certain gap … Meer weergeven The disjunctive graph is one of the popular models used for describing the job-shop scheduling problem instances. A mathematical statement of the problem can be … Meer weergeven Scheduling efficiency can be defined for a schedule through the ratio of total machine idle time to the total processing time as below: $${\displaystyle C'=1+{\sum _{i}l_{i} \over \sum _{j,k}p_{jk}}={C.m \over \sum _{j,k}p_{jk}}}$$ Meer weergeven Graham had already provided the List scheduling algorithm in 1966, which is (2 − 1/m)-competitive, where m is the number of machines. Also, it was proved that List scheduling is optimum online algorithm for 2 and 3 machines. The Coffman–Graham algorithm (1972) … Meer weergeven
