This study focuses on the carrying capacity estimation for Darkesh forest in Northeast Iran. Four factors were used for estimating the carrying capacity including tourist flows, size of the area, optimum space available for each tourist, and visiting time. Results showed that the physical carrying capacity was 2727 ha or 165 visitors/day, while the real carrying capacity was 2719 ha or 132 visi...

In this paper we study a periodic review single item single stage inventory system with stochastic demand. In each time period the system must order none or at least as much as a minimum order quantity Qmin. Since the optimal structure of an ordering policy with a minimum order quantity is complicated, we propose an easy-to-use policy, which we call (R,S,Qmin) policy. Assuming linear holding an...

This paper studies a capacity management problem with upgrading. A firm needs to procure multiple classes of capacities and then allocate the capacities to satisfy multiple classes of customers that arrive over time. A general upgrading rule is considered, i.e., unmet demand can be satisfied using multistep upgrade. No replenishment is allowed and the firm has to make the allocation decisions w...

In this competitive marketplace, businesses seeking to maximize profitable outcomes need to ensure their information technology (IT) systems are robust in order to deliver uninterrupted application availability. This is significant for enterprises as high performance of business appli cations is an underlying driver of business growth. Accordingly, the top priority for system administrators is ...

Cloud computing provides the illusion of a seamless, infinite resource pool with flexible on-demand accessibility. However, behind this illusion there are thousands of servers and peta-bytes of storage, running tens of thousands of applications accessed by millions of users. The management of such systems is non-trivial because they face elastic demand, have heterogeneous resources, must fulfil...

Long term capacity planning involves locating and allocating the production capacities and inventory capacities, and short term capacity planning involves the production allocation and distribution of materials. Most existing literature deals with them individually and also consider only investments in capacities and do not consider disinvestment. Combining the above problems into one would giv...

This paper studies the potential benefits of collaborative forecasting (CF) partnerships in supply chains that are capacity-constrained. Our supply chain consists of a manufacturer and a retailer, that operate in an information-rich environment, where one or both of them may be privy to valuable information that can be used to resolve demand uncertainty. To reflect the reality in capacity-const...

Proof. The first inequality follows from the fact that any allocation of capacity that is feasible in NV is also feasible in DYN, while DYN has the additional freedom to substitute products. The second follows from the fact that for a given demand realization D1,D2, ...,DT , any allocation decision available in DYN is also a feasible allocation in STC. In addition, there are allocation opportun...
