Today’s global economy relies heavily on transportation and warehousing to deliver goods. Outsourcing has made the distribution networks complex with several layers of national (import) distribution centers (NDCs) and regional distribution centers (RDCs) between suppliers and retailers. More distribution nodes in the supply chain also means more inventory stockpiles. We present an integrated fa...

BACKGROUND The creation of successful health policy and location of resources increasingly relies on evidence-based decision-making. The development of intuitive, accessible tools to analyse, display and disseminate spatial data potentially provides the basis for sound policy and resource allocation decisions. As health services are rationalized, the development of tools such graphical user int...

There is mounting pressure on healthcare planners to manage and contain costs. In rural regions, there is a particular need to rationalize health service allocation to ensure the best possible coverage for a dispersed population. Rural health administrators need to be able to quantify the population affected by their allocation decisions and, therefore, need the capacity to incorporate spatial ...

We consider the problem of allocating personal protective equipment, namely surgical and respiratory masks, to health centers under extremely limited supply. formulate a multi-objective multi-period non-linear resource allocation model for this with objectives minimizing number infected workers, patients deprivation cost function defined over shortages. solve resulting using ε-constraint algori...

in this paper, we develop a capacitated location-covering model considering interval values for demand and service parameters. we also consider flexibility on distance standard for covering demand nodes by the servers. we use the satisfaction degree to represent the constraint of service capacity. the proposed model belongs to the class of mixed integer programming models. our model can be redu...
