end{aligned} (1)The FJSP scheduling problem is divided into two sub-problems: The operations assignment sub-problem assigns each operation to an appropriate machine.
The part operation assignments to machines and the machines assignments to cells are also shown in Fig. 2.
This problem encompasses various types of flexibility aspects pertaining to part selection and operation assignments along with constraints ranging from simple algebraic to potentially very complex conditional constraints.
Furthermore, the operation scheduling problem, the FJSP presents an additional difficulty caused by the operation assignment problem to a set of available machines.
In CPSO-LP, decision variables corresponding to part routing selection and part operation assignment are fixed and other variables are allowed to be changed.
The overall problem is composed of tightly-coupled subproblems, i.e., determining the allocation of operators that execute the operations, the assignment of operations to operators, and scheduling of the operations.
However, war loomed and Challis joined the RAF Film Production Unit and refocused his talents to film operations abroad, assignments which took him to Casablanca, Lisbon and the Hague.
A candidate's fitness for duty is assessed by a military practitioner, who is the only person fully aware of the realty of requirements for the various operations and assignments involved.
This paper discusses the first-ever system design of a 3D CAD system on a smart device, the selection of the modeling operations, the assignment of gestures to these operations, and use of operation modes.
In optimization and operations research, assignment problems (also known as maximum-weight matching problems) are mathematical models that describe how to pair items from two different categories (Kuhn, 1955; Munkres, 1957).
