This paper describes the development of a questionnaire for evaluating usability during EHR system procurement (DPUQ). Established usability questionnaires can be used to gather user feedback after using the systems. However, during procurement, experimenting with real system use is practical only with a limited number of system candidates. There is a need for less resource-demanding usability ...

Social Media (SM), in recent years, is emerging as a common platform for low cost information exchange, and has attracted a critical mass of users both at corporate and retail levels. Theoretically, SM can thus be used as a tool to strengthen e-procurement in the public sector. Towards this end, we have prepared a conceptual model drawing on literature reviews and some examples while identifyin...

during the implementation, construction projects usually encounter situation that considerably affects the project scheduling and cost. this study aims at using an improved version of the harmony search algorithm (hsa) to schedule resource constrained construction projects. this model is formulated as a global optimization problem. it will determine the duration of each activity to minimize the...

In theory, combinatorial auctions can provide significant benefits in many real-world applications, such as truckload procurement. In practice, however, the use of such auctions has been greatly limited by the need for bidders to bid on an exponential number of bundles and for the auctioneer to solve an exponentially large winner-determination problem. We address these challenges for VCG combin...

This paper presents a positive theory about the contractual form of procurement contracts under cost uncertainty. While the cost of manufacture is uncertain it can be controlled, to an extent depending on the effort exerted by the agent. The effort exerted by the agent is not contractible but causes disutility to the agent. Hence, the amount of effort exerted depends on the power of incentives ...

The authors discuss procurement and provision of pharmaceutical products from the perspective of supply management in the public health sector, focusing on two main aspects: quality and cost. The article analyzes issues to be considered by buyers when evaluating drug quality, especially formulation stability, bioequivalence, and the role of generics. Also discussed are factors involving costs a...

Although a considerable amount of documentation has been published on the alleged benefits of Enterprise Resource Planning (ERP) systems, rigorous theoretically supported research into this topic has been limited. Furthermore, with the recent popularity of new technologies such as those supporting Business-to-Business (B2B) e-procurement, many have begun to loose focus of the underlying infrast...

In the past decade, electronic mechanisms have started to overtake the conventional methods of procurement for both governments and enterprises because of the cost and time saving effects of e-procurement. Economic theory suggests that the success of e-procurement depends on the number of bidders who participate in procurement auctions. In this paper, the authors investigate the cultural factor...
