Sistema de apoio à decisão para o reaprovisionamento intercontinental

Este estudo foi desenvolvido em contexto empresarial e apresenta o levantamento de uma oportunidade de melhoria conjunta nos processos de gestão de stocks, compras e logística com o objetivo de otimizar a seleção e envio dos artigos com necessidade de reposição. O caso de estudo apresentado neste documento retrata o circuito logístico entre uma empresa sediada em Angola e outra em Portugal. A primeira dedica-se à venda por grosso e a retalho que é fornecida pela segunda, onde também está concentrada a gestão de aprovisionamento. Integrando uma sociedade menos desenvolvida como Angola, a delicadeza e complexidade dos problemas associam-se à incerteza, tornando um ambiente propício para a identificação e implantação de melhorias nos processos de decisão, colmatando a dependência de apoio em sistemas e serviços externos. Com uma logística de abastecimento intercontinental, a seleção e envio de mercadoria é uma preocupação dos gestores, uma vez que o tempo de fornecimento é longo e poderá afetar a performance das vendas caso seja uma decisão não sustentada. Com o foco no apoio à decisão, desenvolveu-se uma ferramenta que incorpora os detalhes da atividade empresarial que permite selecionar os artigos para reposição, maximizando o seu potencial valor de vendas.

Developing and validating a measure of the strength of the HRM system: Operationalizing the construct and relationships among its dimensions

The four studies in this article introduce a questionnaire to measure Strength of the HRM System (HRMSQ), a multidimensional construct, theoretically developed by Bowen and Ostroff (2004). Strength of the HRM System is a set of process characteristics that lead to effectiveness in conveying signals to employees that allow them to create a shared meaning of desired and appropriate work behaviours. Nine characteristics are suggested, grouped in three features: Distinctiveness, Consistency and Consensus. Study 1 developed and tested a questionnaire in a sample of workers from five different sectors. Study 2 cross-validated the measure in a sample of civil servants in a municipality. These two studies used performance appraisal as the reference HRM practice and led to a short version of the HRMSQ. Study 3 and Study 4 extend the HRMSQ to several common HRM practices. The HRMSQ is tested in two samples, of call center and several private and public organizations‟ workers (study 3). In study 4 the questionnaire is refined and tested with a sample from a hotel chain and finally cross-validated with two other samples, in the insurance and batteries sectors, leading to a longer version of the HRMSQ. Content analysis of several interviews with human resource managers and the Rasch model (1960, 1961, 1980), were used to define and select the indicators of the questionnaire. Convergent, discriminant and predictive validity of the measure are tested. The results of the four studies highlight the complexity of the relationships between the proposed characteristics and support the validity of a parsimonious measure of Strength of the HRM System.
