In grocery retail supply chains, a single retailer with a large market share is delivered by many suppliers. For replenishment decisions the retailer (or the supplier in case of Vendor Managed Inventory) has to make a tradeoff between keeping more inventory or using a higher replenishment frequency. In models studying this tradeoff inventory and transportation capacities are often fixed and costs...
Agent_Zero is a formal alternative to the rational actor model that has dominated social science since the 1940s. This software individual is the first to be endowed with distinct affective, deliberative, and social modules. Grounded in neuroscience, these internal facets interact to produce far-from-rational individual behavior. And when ensembles of these agents interact spatially they generate...
International Community can decide to establish several types of sanctions on the economy of a country. No matter the reasons of these sanctions, generally, they can have many adverse effects on the economy of the sanctioned country. This depends on the variety and extent of the sanctions. We propose a system dynamics model to capture some of the main reasons behind the economic instability in a sanctioned...
Innovation and health-care funding reforms have contributed to the deployment of Information and Communication Technology (ICT) to improve patient care. Many health-care organizations considered the application of ICT as a crucial key to enhance health-care management. This paper aims at providing a global methodology to assess the organizational impact of high-level Health Information System (HIS)...
Entrepreneurial support organizations are among the most successful approaches for economic growth. There are multiple dimensions of entrepreneurial support activities such as resource provision, funding or networking support. In this paper, we present an approach for the assessment and analysis of entrepreneurial support for networking and its effects on global innovation ecosystems. The innovation...
Educational simulation is concerned with the use of all suitable forms of simulation, including simulation games, in education. Focusing on management science and economics, we analyze a choice of simulation models for identifying opportunities how to turn them into educational simulations. As a result of our analysis, we propose a framework for classifying and building different types of educational...
A variable annuity is an insurance contract that contains financial guarantees. Due to the complexity of guarantees, there are no closed-form formulas to calculate the value of these guarantees. Insurance companies rely heavily on Monte Carlo simulation to calculate the value of the guarantees. However, almost all simulation software for variable annuity is proprietary, posing a substantial barrier...
The increasing number of geriatric patients is one of the most important problems for the next years. This kind of patients is often dependent and does not tolerate environment changes so that hospitalization can strongly deteriorate the elderly health state. This paper focuses on two services of the geriatric services: the Short Stay (Acute Care) and Rehabilitative Care (to prepare the return at...
Stroke is major cause of disability internationally, the leading cause of disability in England, and the third most common cause of death worldwide. The good news is that there is growing evidence that simulation modeling can play an important role in understanding and designing improvements in acute stroke systems in order to reduce this disability burden. This paper presents an overview of simulation...
For pragmatic reasons, cost-effectiveness analyses performed for NICE Clinical Guidelines use a piecemeal approach, evaluating only selected aspects of diagnosis, treatment or care. A Whole Pathway approach, considering diagnosis-to-death, may provide more realistic estimates of costs and health outcomes, taking account of the healthcare context and individual risk factors, history and choices for...
