Purpose: Providing timely access is an important measure of patient satisfaction in specialty care clinics such as cancer centers. Excessive patient wait time to see an oncologist is very critical for cancer patients as they often benefit from starting the treatment process as soon as possible....

This paper is concerned with demand planning for internal supply chains consisting of workstations, production facilities, warehouses, and transportation links. We address the issue of how to help a supplier firmly accept orders and subsequently plan to fulfill demand. We first formulate a...

Vor dem Hintergrund des russischen Angriffskriegs suchen immer mehr Familien aus der Ukraine Schutz in Deutschland. Am 5. Mai 2022 waren rund 242.000 geflüchtete Minderjährige aus der Ukraine in Deutschland registriert und die Fluchtzuwanderung setzt sich weiter fort. So dürften sich...

Background: The key performance index for the container terminals is the vessel berthing time which is highly affected by the scheduling of the different handling equipment. Proper integrated scheduling of the handling equipment is crucial, especially in automated container terminals, where all...

We study an infinitely repeated oligopoly game in which firms compete on quantity and one of them is capacity constrained. We show that collusion sustainability is non-monotonic in the size of the capacity constrained firm, which has little incentive to deviate from a cartel. We also present...

Motivated by the problems of imbalance between the supply of and demand for the different levels of hospitals in a hierarchical healthcare system, we propose two contract mechanisms: patient subsidy and capacity investment. Under the patient subsidy scheme, each patient who chooses the primary...

In this paper, we consider the multi-period joint capacity allocation and job assignment problem. The goal of the planner is to simultaneously decide on allocating resources across the J different supply nodes, and assigning of jobs of I different demand origins to these J nodes, so as to...

We study the abilities of competitive markets to produce sufficient energy capacities to meet a fixed energy demand. Renewable energy producers with stochastic outputs and no variable costs compete against conventional energy producers with deterministic, pollutant outputs and increasing...

This chapter evaluates state capacity from a long-run historical perspective. We discuss how to define and measure state capacity. We explain how the establishment of a high-capacity state can enhance domestic peace, improve material prosperity, and promote more pluralistic norms. We describe...

We investigate how capacity payments in combination with scarcity pricing of energy can ensure resource adequacy in electricity markets, defined as the ability of supply and other resources to provide enough energy and capacity to meet demand under steady-state operating conditions. This work...

Partial vertical ownership describes a situation in which a firm holds financial shares in either its supplier (referred to as partial backward integration) or its customer (partial forward integration). We study the effect of such financial interconnectedness on two operational decisions:...

Adhesion of type-P and type-1 fimbriated uropathogenic E. coli (UPEC) to uroepithelial cells initiates urinary tract infections (UTIs). This research aimed to evaluate the capacities of cranberry polyphenols and their microbial metabolites to inhibit such adhesion in vitro using a modified...

The planning practice of health care capacities suffers from sectoral and regional constraints and it remains difficult to ensure an equal access for patients. Moreover, standard planning approaches lack the choice-theoretic grounding necessary for making reliable predictions of the demand and...

Investment decisions in competitive power markets are based upon thorough profitability assessments. Thereby, investors typically show a high degree of risk aversion, which is the main argument for capacity mechanisms being implemented around the world. In order to investigate the...

The planning practice of health care capacities suffers from sectoral and regional constraints and it remains difficult to ensure an equal access for patients. Moreover, standard planning approaches lack the choice-theoretic grounding necessary for making reliable predictions of the demand and...

Purpose: The theory of constraints (TOC) drum-buffer-rope methodology is appropriate when managing a production plant in complex environments, such as make-to-order (MTO) scenarios. However, some difficulties have been detected in implementing this methodology in such changing environments. This...

Many electricity markets use capacity mechanisms to support generation owners. Capacity payments can mitigate imperfections associated with "missing money" in the spot market and solve transitory capacity shortages caused by investment cycles, regulatory changes, or technology shifts. We discuss...

In the European Union's (EU) gas transmission system the relative prices of short-term transmission capacities are specified via factors called multipliers. Previous literature indicates that, depending on the region, there exist optimal multiplier levels that can allow transport tariffs to be...

Demand forecasting and capacity management are complicated tasks for emergency healthcare services due to the uncertainty, complex relationships, and high public exposure involved. Published research does not show integrated solutions to these tasks. Thus, the objective of this paper is to...

Supply chain resilience (SCR) is often seen as a dynamic capability that enables firms to effectively cope with disruptions and unforeseen events in the business environment. However, empirical research focusing on influencing factors on SCR is still limited. Based on the resource-based view...
