A Queueing Model For Customer Rescheduling And No-Shows In Service Systems, Yue Tang, Houyuan Jiang, Jingui Xie, Zhichao Zheng

Research Collection Lee Kong Chian School Of Business

We study an M/M/1/K queue where customers can reschedule their appointments. Rescheduled customers show up with higher probabilities, incurring lower no-show costs, but rescheduling also frees up slots that may not be filled later, leading to wasted service capacity and lower throughput. The system manager aims to minimize the long-run average cost by controlling rescheduling policies. We derive conditions under which rescheduling should be allowed for different scenarios depending on whether customers can reschedule only once or multiple times.

How Random Incidents Affect Travel-Time Distributions, Melike Baykal-Gürsoy, Andrew Reed Benton, Pedro Cesar Lopes Gerum, Marcelo Figueroa Candia

Supply Chain Management

We present a novel analytical model to approximate the travel-time distribution of vehicles traversing a freeway corridor that experiences random quality of service degradations due to non-recurrent incidents. The proposed model derives the generating function of travel times in closed-form using clearance time, incident frequency and severity, and other ordinary traffic characteristics. We validate the model using data from a freeway corridor where weather events and traffic accidents serve as the principal causes of service degradation. The resulting model is equivalent in performance to widely used methodologies while uniquely providing a clear connection on how incidents affect travel time distribution. …

Dynamic Crop Allocation In The Presence Of Two-Season Crop Rotation Benefits, Onur Boyabatli, Javad Nasiry, Yangfang Zhou

Research Collection Lee Kong Chian School Of Business

The objective of this chapter is twofold. First, to study how a farmer should dynamically allocate farmland between two crops when the crops have rotation benefits across growing seasons, i.e., when it is more profitable to grow a crop on rotated farmland (where the other crop was grown) than on non-rotated farmland (where the same crop was grown). Second, to develop a practically implementable heuristic allocation policy and examine its performance in comparison with other heuristic policies commonly suggested in the literature. While the chapter is based on our companion paper (Boyabatlı et al (Management Sci 65(5):2060–2076, 2019)), we characterize …

Resource Capacity Requirement For Multi-Terminal Cooperation In Container Ports, Byung Kwon Lee, Mei Wan Low

Research Collection Lee Kong Chian School Of Business

Capacity sharing among neighboring terminals offer a means to meet increasing or unexpected demand for cargo-handling without additional capital investment. This study proposes a model for capacity requirement planning of major resources, such as quay cranes (QCs), storage space, and gate, in multiterminal port operations where demand is time dependent. A resource profile simulation is run to generate random events across the terminals and estimate the capacity requirement in the form of workload distributions on port resources over time-shifts. The effects on workload requirement, arising from multiterminal cooperation, are subsequently evaluated in consideration of different container flows among terminals. Experimental …
