Abstract
This paper describes a case study in a chemical company in which management was concerned with low productivity and the inability to keep pace with demand. A description of the company and an assessment of its competitiveness are outlined. To improve productivity and to help management solve the firm’s production scheduling problem, a proposal was developed based on the travelling salesman problem with adjustments for earliness and lateness costs over due dates of the orders. Management involvement is discussed.

The purpose of this article is to develop a methodology for the identification of a desired normative scenario, acceptable and feasible, based on a set of prospective scenarios.
Abstract
Purpose
The purpose of this article is to develop a methodology for the identification of a desired normative scenario, acceptable and feasible, based on a set of prospective scenarios.
Design/methodology/approach
This paper presents strategic alliances as one fundamental tool in the process of constructing the future. The alliances are based on prospective scenarios, within strategic interactions.
Findings
The central key is the view of the most probable future as a NASH balance point. This point identifies not only a balance of forces, but also the negotiation limits for each actor and therefore the strategic alliances possible. The alliances, if achieved, create a “super actor”, destabilizing the original balance, and creating a new balance point, and therefore a more likely new future.
Originality/value
This article develops a methodology for the identification of a desired normative scenario, acceptable and feasible, based on a set of prospective scenarios.

Abstract
Logistical facility location decisions can make a crucial difference in the success or failure of a company. Geographical Information Systems (GIS) have recently become a very popular decision support system to help deal with facility location problems. However, until recently, GIS methodologies have not been fully embraced as a way to deal with new facility location problems in business logistics. This research makes a framework for categorizing empirical facility location problems based on the intensity of the involvement of GIS methodologies in decision making. This framework was built by analyzing facility location models and GIS methodologies. The research results revealed the depth of the embracement of GIS methodologies in logistics for determining new facility location decisions. In the new facility location decisions, spatial data inputs are almost always coupled with the visualization of the problems and solutions. However, the usage of GIS capability solely (i.e. suitability analysis) for problem solving has not been embraced at the same level. In most cases, the suitability analysis is used together with special optimization models for choosing among the multiple alternatives.
