Introduction As many authors, in different ways and contexts have remarked (Azzone and Cainarca, 1991; Azzone et al., 1992; Brandolese, 1994; Newall and Dale, 1991) knowledge regarding quality has evolved, both in terms of research and practical achievements. ...

The research focuses on the assessment of the Information System (IS) currently implemented in the considered organizations and aims at identifying strengths, weaknesses or inconsistencies, obtaining useful information in order to address new IT investment and to improve user

Moreover, the paper presents the preliminary results obtained by applying the new methodology

WIP reduction and throughput enhancement are pursued through the integration of group technology and scheduling techniques, to jointly and globally perform the setup time minimization and the workload balance maximization, together with a lot size reduction. A first prototype of the discussed framework is run on real assembly line data together with a simulation model in order to perform a validation test of the system.

The objective of the method is to identify at each assembly stage a set of families which both minimizes setups and maximizes workload balance. The adopted search strategy defines a bidimensional space of solutions and identifies the families that exploit in the most balanced way each of the available resources, that is: production capacity and component feeders space. Results of the application of the proposed method to a real case are evaluated using as a benchmark another heuristic with the same objectives.

The well-known minimum-setup rule is shown not to be a fair dispatching strategy; moreover, some evidence is given about its predisposition to pursue local optimum sequences. a new setup-saving dspatchin rule named Maximum Capacity Gain (MCG) was designed, that overrides the above mentioned shortcomings of the minimum setup. The two dispatching rules were then comparatively evaluated by means of a detailed simulation model of a job shop. The maximum capacity gain rule is shown to both achieve a larger setup time reduction, and to behave more fairly than minimum setup. Evidence is also given that these advantages increase in the manufacturing contexts where there are more opportunities of reducing setup times.

The standpoint for this new method lies in the following remarks: (i) comparisons among ORR models should be performed in dynamic and uncertain environments; (ii) ORR techniques robustness toward the shop uncertainty and perturbations should be considered and (iii) ORR models should be compared by changing their features one at a time, instead of comparing completely different ORR techniques. Consistently, we present a comparison among three ORR models, previously developed in literature, aimed at investigating: (i) the impact of a dynamic and uncertain environment on the performances achieved; (ii) the robustness of these ORR models when facing some environmental perturbations, like the system workload, the mix imbalance, the machine unavailability and the processing time variability, that usually take place in real life job shops; (ii...

This need of robust methodologies for shop floor planning, being possible by actual powerful information systems and high– performance hardware devices, is relevant also for small firms operating in high competition and high turnover market, that should solve their own production planning problem profitably, exploiting the nowadays available theoretical models. The main objective of this work is to develop and test an on-line computer tool designed to support managerial decisions in optimizing the shop floor schedule in an Italian manufacturing SME, encompassing a group of single machines environment. The selection of a set of relevant performance indicators is done and a data collection activity is carried out in order to depict the as-is scenario; then, static calculations estimate impro...

The article introduces a set of management techniques and supporting tools that can be used to analyse and describe SCM strategies. It proposes a new normative tool and uses it to examine a large set of relevant SCM case studies pertaining to seven industries: apparel, automobile, grocery, white goods, pharmaceuticals, computers and book publishing. The article develops a new conceptual framework for SCM strategies and test it based on empirical evidence. The new schemes proposed here provide a normative tool to define and represent supply chain strategies, a contingency model to support managers in designing supply chain strategies, and some hints for further research.
