MATHEMATICAL MODELS AND POLYHEDRAL STUDIES FOR INTEGRAL SHEET METAL DESIGN

We deal with the optimization of the production of branched sheet metal products. New forming techniques for sheet metal give rise to a wide variety of possible profiles and possible ways of production. In particular, we show how the problem of producing a given profile geometry can be modeled as a discrete optimization problem. We provide a theoretical analysis of the model in order to improve its solution time. In this context we give the complete convex hull description of some substructures of the underlying polyhedron. Moreover, we introduce a new class of facet-defining inequalities that represent connectivity constraints for the profile and show how these inequalities can be separated in polynomial time. Finally, we present numerical results for various test instances, both real-world and academic examples.

How did the crisis affect small and medium-sized enterprises? -- from a field study of the metal-working industry in Java

This paper focuses on the impact of Indonesia's economic crisis on small and medium-sized enterprises (SMEs). It shows how the performance of SMEs during the crisis varied widely even in the same industrial subsector, and found that the factors most affecting performance have been market orientation and the linkages that the SMEs have formed with the buyers of their products. Well-performing SMEs were found to have utilized putting-out linkages with wholesalers which enabled them to switch to products having better markets. On the other hand, the SMEs which had subcontracting linkages with assemblers or contracting linkages with user-factories (with the exception of SMEs having export-oriented linkages) suffered badly in the crisis because of specificity of products with little room for switching. The paper also found that exposure to debt due to borrowing for investment has been another factor affecting performance, but that enterprise size has had no linear correlation with performance.

A continuous-time MILP model for short-term scheduling of make-and-pack production processes

In process industries, make-and-pack production is used to produce food and beverages, chemicals, and metal products, among others. This type of production process allows the fabrication of a wide range of products in relatively small amounts using the same equipment. In this article, we consider a real-world production process (cf. Honkomp et al. 2000. The curse of reality – why process scheduling optimization problems are diffcult in practice. Computers & Chemical Engineering, 24, 323–328.) comprising sequence-dependent changeover times, multipurpose storage units with limited capacities, quarantine times, batch splitting, partial equipment connectivity, and transfer times. The planning problem consists of computing a production schedule such that a given demand of packed products is fulfilled, all technological constraints are satisfied, and the production makespan is minimised. None of the models in the literature covers all of the technological constraints that occur in such make-and-pack production processes. To close this gap, we develop an efficient mixed-integer linear programming model that is based on a continuous time domain and general-precedence variables. We propose novel types of symmetry-breaking constraints and a preprocessing procedure to improve the model performance. In an experimental analysis, we show that small- and moderate-sized instances can be solved to optimality within short CPU times.

El sector industrial del Gran La Plata en el neoliberalismo : Aproximación a sus transformaciones a través de los Censos Nacionales Económicos

El presente trabajo pretende abordar los cambios de la industria manufacturera de la Microrregión Gran La Plata en el contexto de implementación de las políticas neoliberales y caracterizar al sector industrial resultante, sobre la base de información de los Censos Nacionales Económicos (cne) de 1974, 1994 y 2004/2005. Partiendo de una lectura de diferentes estudios sobre el tema, se presenta una caracterización general de las transformaciones del sector a escala nacional, con particular atención en la década de los años noventa. Desagregando el sector industrial y focalizándose en las variaciones intercensales del número de locales industriales, se observa que, en sintonía con la escala nacional, las actividades de las ramas metalmecánicas y textil presentan disminuciones significativas. Paralelamente, se mantuvo y/o creció el número de establecimientos dedicados a la fabricación de productos intermedios, como refinación de petróleo, productos petroquímicos, químicos y plásticos, y la de metales comunes. Esto se habría enmarcado en el aumento de estas ramas en el perfil productivo del país, que, en los años 90, se especializó en la elaboración de commodities
