Opis:
The problem considered in the paper is motivated by production planning in a foundry equipped with the furnace and casting line, which provides a variety of castings in various grades of cast iron/steel for a large number of customers. The quantity of molten metal does not exceed the capacity of the furnace, the load is a particular type of metal from which the products are made in the automatic casting lines. The goal is to create the order of the melted metal loads to prevent delays in delivery of goods to customers. This problem is generally considered as a lot-sizing and scheduling problem. The paper describes two computational intelligence algorithms for simultaneous grouping and scheduling tasks and presents the results achieved by these algorithms for example test problems.

Opis:
The paper presents a scheduling production problem in foundry equipped with one furnace and two casting lines, which provides a number of different types of castings for a large number of clients. The amount of molten metal may not be greater than the capacity of the furnace and its load is a type of metal, from which the products are manufactured on automated casting lines. The purpose of planning is to create the processing order of metal, to prevent delays in the delivery of the ordered products to the customers. This problem is mixt of lot-sizing problem and scheduling problem on two machines (the lines) running in parallel. The article gives a mathematical model, which formally defines the optimization problem, and his relaxed version which is based on the concept of rolling-horizon planning. The proposed approaches were tested on the sample data.

Opis:
Mathematical programming, constraint programming and computational intelligence techniques, presented in the literature in the field of operations research and production management, are generally inadequate for planning real-life production process. These methods are in fact dedicated to solving the standard problems such as shop floor scheduling or lot-sizing, or their simple combinations such as scheduling with batching. Whereas many real-world production planning problems require the simultaneous solution of several problems (in addition to task scheduling and lot-sizing, the problems such as cutting, workforce scheduling, packing and transport issues), including the problems that are difficult to structure. The article presents examples and classification of production planning and scheduling systems in the foundry industry described in the literature, and also outlines the possible development directions of models and algorithms used in such systems.

Opis:
The problem considered in the paper is motivated by production planning in a foundry equipped with a furnace and a casting line, which provides a variety of castings in various grades of cast iron/steel for a large number of customers. The goal is to create the order of the melted metal loads to prevent delays in delivery of goods to customers. This problem is generally considered as a lot-sizing and scheduling problem. However, contrary to the classic approach, we assumed the fuzzy nature of the demand set for a given day. The paper describes a genetic algorithm adapted to take into account the fuzzy parameters of simultaneous grouping and scheduling tasks and presents the results achieved by the algorithm for example test problem.

Opis:
The paper describes a complete framework that uses a multi-agent approach for production scheduling in a foundry. Different types of autonomous agents have been designed, each playing a different role in the supply chain management of the fodundry, along with their responsibility and behavior in the system. In order to generate a proper and reliable schedule the agents negotiate with each other by sending messages compliant to FIPA ACL standard. A prototype of the system has been implemented in JADE and allowed to conduct preliminary simulation of the system. Although some agents some agents have been omitted in the prototype, it was possible to verify the main assumptions of the system, as well as, to indicate and discuss potential problems with its implementation into production practice.

Opis:
The paper presents a novel Iterated Local Search (ILS) algorithm to solve multi-item multi-family capacitated lot-sizing problem with setup costs independent of the family sequence. The model has a direct application to real production planning in foundry industry, where the goal is to create the batches of manufactured castings and the sequence of the melted metal loads to prevent delays in delivery of goods to clients. We extended existing models by introducing minimal utilization of furnace capacity during preparing melted alloy. We developed simple and fast ILS algorithm with problem-specific operators that are responsible for the local search procedure. The computational experiments on ten instances of the problem showed that the presence of minimum furnace utilization constraint has great impact on economic and technological conditions of castings production. For all test instances the proposed heuristic is able to provide the results that are comparable to state-of-the art commercial solver.
