Outsourcing is related to the action which an organization deals with its suppliers through a kind of business contract where a specific activity or service has been hired to be made. The outsourcing of some activities has become a common practice in the industry, nowadays. It reduces costs, significantly, in the production process and, at the same time, adds some values to the business organization. However it is necessary to measure the performance of these activities. Data Envelopment Analysis (DEA) is a non-parametric method useful to measure comparative performance. It has a wide range of applications measuring comparative efficiency. The Analytic Hierarchy Process (AHP) is a multiple criteria decision-making method that uses hierarchic structures to represent a decision problem and then develops priorities for the alternatives based on the decision-maker's judgments. This paper presents an integrated application based on DEA and AHP to evaluate the efficiency of subcontracted companies in a Brazilian aerospace factory. © 2007 Springer-Verlag London Limited.

A Digital Factory is a concept which improves the collaboration among product development processes. Despite the benefits brought by this concept, failures may occur in its implementation. This paper aims to present the Critical Success Factors in the implementation of a Digital Factory project in a Brazilian company. These factors were identified by an exploratory survey on the implementation of Enterprise Resource Planning and Product Lifecycle Management among other systems. Following this identification, the factors were prioritized using the Delphi Method and the Analytic Hierarchy Process; this evaluation was carried out by professionals from enterprises which implement Digital Factory projects, in Brazil and abroad. Nine factors were identified. The five main priorities were: Continuous Support and Commitment from Top Management; Comprehensive Business Reengineering; Skilled and Experienced Partners; Participation and Commitment of Users; and Appropriate Role of the Project Manager.

The lack of risk management can generate disruption in the supply chain, and there is little literature related to the aerospace industry. This article aims at identifying the risk factors for supply chain of the main Brazilian aircraft manufacturer. Nine risk factors specific to aircraft manufacturers were identified: Environmental, Natural and Political, Supply Chain, Business Strategy, Product Management, Indicators, Organization, Productivity, and Quality and Information System. These factors were quantitatively evaluated with respect to their criticality using the Analytic Hierarchy Process (AHP). The Quality and Productivity factors were considered the most relevant in this study, which can be classified as a single case study. The necessary data were obtained through interviews with professionals from different areas of the studied enterprise.

Lâaudit, câest un outil de gestion très important pour que les organisations puissent accomplir la réussite. Selon le fait quâil nây a pas des modèles dâaide à lâaudit, il existe une opportunité de recherche. En considerant les Méthodes dâAide à la Décision, il y a des plusieurs type dâapplications. Lâobjectif de la recherche câest la proposition dâun modèle capable de sélectionner des processus pour faire lâaudit dans une distributeur de carburant en considerant la prise de décision en groupe. La modélisation normative empirique câest la méthode de recherche utilisée. Un modèle qui utilise lâAnalytic Hierarchy Process (AHP) et la prise de décision en groupe a été proposé face aux difficultés dâun département dâAudit Interne. Le modèle proposé présente les poids des processus et permet leur priorisations dans un scénario determiné. Pour lâapplication de ce modèle présenté, on a utilisé cinq critères et 26 alternative (processus). Lâinformation de jugement a été bien founi par trois spécialistes du département. Quelques rendez-vous avec les participants ont été pris pour obtenir et réviser les donnés ainsi que discuter les résultats. Les résultats obtenus par le modèle permettent dâidentifier les processus quâil faut plus dâattention. Lâéquipe a considéré le modèle comme une proposition dâaide à la prise de décision très pertinent pour le département dâAudit Interne
