A General Disjunctive Model for the Retrofit of Multiproduct Batch Plants
نویسندگان
چکیده
The retrofit of multiproduct batch plants treats the modification of the original configuration of the plant to satisfy new production conditions (new products, new demand pattern, etc.). A disjunctive model is presented to solve this problem that includes all the usual alternatives in this kind of problems. A disjunction is generated for each batch stage considering all the feasible configuration alternatives for old and new units. Each disjunction term contains all constraints to model the batch stage options: operation time, units sizing and cost, etc. In a similar way, a disjunction is generated for the allocation of intermediate storage tanks. Several examples were solved, the computational performance of this approach is compared with the conventional formulation.

Disjunctive Multiperiod Optimization Methods for Design and Planning of Chemical Process Systems
In this paper, we present a general disjunctive multiperiod nonlinear optimization model, which incorporates design, as well as operation and expansion planning, and takes into account the corresponding costs incurred in each time period. This model is formulated with the use of logic and disjunctive programming, and includes Boolean variables for design, operation planning and expansion planni...
متن کاملA disjunctive programming model and a rolling horizon algorithm for optimal multiperiod capacity expansion in a multiproduct batch plant
In this paper we address a multi-period mixed integer non-linear problem for the capacity expansion of multiproduct batch plants. In this problem, given a certain batch plant with its current configuration, product recipes, and growing production targets, modular expansions are wanted so that new demand can be met. Unlike most work for the batch retrofit problem found in literature, a multi-per...
متن کاملMultiperiod production planning and design of batch plants under uncertainty
A two-stage stochastic multiperiod LGDP (linear generalized disjunctive programming) model was developed to address the integrated design and production planning of multiproduct batch plants. Both problems are encompassed considering uncertainty in product demands represented by a set of scenarios. The design variables are modeled as here-and-now decisions which are made before the demand reali...
متن کاملOptimal Multiperiod Design and Operation of Multiproduct Batch Plants
New alternatives for the multiperiod design and operation planning of multiproduct batch plants are presented. Unlike previous works, this approach configurates the plant in every period considering the assignment of parallel units of different sizes operating either in or out-of-phase. The objective function maximizes the net profit considering incomes, investment costs, and both product and r...
متن کاملStochastic evaluation and optimization of flexibility in multiproduct batch plants
This paper deals with the problem of evaluating and optimizing a stochastic measure that integrates flexibility and reliability in multiproduct batch plants. It is assumed that uncertainties in the product demands are given in terms of statistical distributions, and that expected failure rates of the equipment are given in terms of discrete probabilities. Based on recent work by the authors (St...
