This paper presents a new MILP mathematical formulation for the scheduling of resource-constrained multiproduct plants involving continuous processes. In such facilities, a sequence of continuous processing steps is usually ...

As there has been a large number of promising developments to the short-term scheduling of batch plants in the last 20 years, the main goal of this work is to provide a general classification of batch scheduling problems ...

The cost-effective routing and scheduling of a fleet of multi-parcel chemical tankers represents a centraldecision making process in both chemical and shipping industry. Ships designed for the transport of liquidor gas in ...

This paper presents a novel column generation algorithm for managing the logistics activities performed by a fleet of multi-parcel chemical tankers. In our procedure, for providing elementary routes, the conventional dynamic ...

A mixed integer linear programming (MILP) for the detailed production planning of multiproduct batch plants is presented in this work. New timing decisions are incorporated to the model taking into account that an operation ...

This paper presents a decomposition algorithm for the integrated scheduling and redesign problem of a multistage batch plant dealing with multipurpose units and heterogeneous recipes. First, the procedure solves the ...

This work introduces the formulation and application of a MILP model to solve the problem of planning the weekly production of a machining plant using numerical control lathes to manufacture spare parts for agricultural ...

The struggle to model and solve Combinatorial Optimization Problems (COPs) has challenged the development of new approaches to deal with COPs. In one of the front lines of such approaches, Operational Research (OR) and ...
