1.每个工件的各操作仅能在某一台机器(集)上加工; 2.所有工件预先给定工艺路线; 3.工件不可重入 job-shop与flow-shop区别 1.job每个工件不需要经过所有机器(集),可以跳过某些工序,而 flow工件需要经过所有工件 ; 2.job中可以对不同工艺路线工件进行加工,而flow要求工件工艺路线完全相同。 https://www....
根据机器加工能力的不同,调度问题可以分为单机调度(single-machine scheduling)、并行机调度(parallel-machines scheduling)、流水车间调度(flow-shop scheduling)、作业车间调度(job-shop scheduling)、柔性作业车间调度(flexible job-shop scheduling)、开放车间调度(open-shop scheduling)等多种类型。 单机调度 单机调度只...

We resolve the complexity status of the relevant problems for the two-machine flow shop, job shop and open shop. A number of approximation algorithms ... C Esswein,JC Billaut,VA Strusevich - 《European Journal of Operational Research》 被引量: 41发表: 2005年 The complexity of flow shop an...
It is shown that the problem of scheduling a two-processor n-job open shop nonpreemptively in order to minimize mean flow time is NP-complete even if input length is measured by the sum of the task lengths. The proof is similar in approach to that used by Garey, Johnson and Sethi to ...
This paper studies two models of two-stage processing with flowshop at the first stage followed by open shop at the second stage. The first model involves multiple machines at the first stage and two machines at the second stage, and the other involves multiple machines at both stages. In ...
This uncommon behaviour of the optimal solution and, consequently, the complexity of the problem studied here, remain open questions, and are challenging topics for future research. 展开 关键词: scheduling proportionate flow shop no-wait total absolute deviations of job completion times ...
Firstly, to make DE suitable for solving flow-shop scheduling problem, a largest-order-value (LOV) rule is used to convert the continuous values of individuals in DE to job permutations. Secondly, a speed-up evaluation method is developed according to the property of the NFSSP with SDSTs ...
shop的计算复杂度低于job shop. 两者的区别也显而易见。除此之外，还有open shop，这里不多赘述。
