A MILP model for an extended version of the Flexible Job Shop Problem [PDF]
, 2014 A MILP model for an extended version of the Flexible Job Shop Scheduling problem is proposed. The extension allows the precedences between operations of a job to be given by an arbitrary directed acyclic graph rather than a linear order.

Flexible Job Shop Problem with Variable Machine Flexibility
IFAC-PapersOnLine, 2019 Abstract We analyze machine flexibility in the context of the flexible job shop problem. In general, the decisions about machine flexibility are taken in advance (the data sets already contain this information). Based on a mathematical model from literature, we proposed an extension that, aiming to minimize the makespan, considers the possibility of ...

Flexible Job Shop Scheduling Problems with Arbitrary Precedence Graphs [PDF]
Production and Operations Management, 2021 A common assumption in the shop scheduling literature is that the processing order of the operations of each job is sequential; however, in practice, there can be multiple connections and finish‐to‐start dependencies among the operations of each job. This paper studies flexible job shop scheduling problems with arbitrary precedence graphs.

Review on flexible job shop scheduling
IET Collaborative Intelligent Manufacturing, 2019 Flexible job shop scheduling problem (FJSP) is an NP‐hard combinatorial optimisation problem, which has significant applications in the real world. Due to its complexity and significance, lots of attentions have been paid to tackle this problem. In this study, the existing solution methods for the FJSP in recent literature are classified into exact ...
