We revisit a service provider's problem to match supply and demand via an online appointment system such as a doctor in the health care sector. We identify in a survey that an extensive set of available appointments leads to significantly less demand because customers infer a lower quality of...

The estimation of costs allocated to each customer when serving them in a collaborative logistic operation is a complex problem whose solution is computationally very expensive. In this work the case of central horizontal collaboration for vehicle routing problems with time windows and a central...

Because customers must usually arrange their schedules to be present for home services, they desire an accurate estimate of when the service will take place. However, even when firms quote large service time windows, they are often missed, leading to customer dissatisfaction. Wide time windows...

For the flexible job shop (FJSP) completion time prediction problem considering environmental noise, the mathematical model of the problem, the sample generator and the completion time prediction model based on AE-CNN-LSTM are constructed. Firstly, to address the problem that workshop data is...

In recent years, patient unpunctuality has become a common problem for mental clinics. The unpunctuality rate has a substantial impact on several quality metrics, including the usage of resources and patient waiting times. Thus, the primary aim of this study is to examine the effectiveness of...

Due to the uncertain nature of the traffic system, it is not trivial for delivery companies to reliably satisfy customers' time windows. To guarantee the reliability of the pickup and delivery service under stochastic and time-dependent travel times, we consider a pickup and delivery problem...

Internet healthcare is becoming increasingly popular, which allows doctor–patient communication through messages, phone calls, or videos. Considering stochastic heterogeneous behaviors of patients and physicians (e.g. time-dependent no-shows, service times), it is critical to determine the...

For the scheduling needs of technicians in IT operations and maintenance services, a study was conducted with the objective of minimizing the total delay of heterogeneous technicians for independent service tasks. An IT technician scheduling model considering task release time is established,...

In transportation and logistic applications, scheduling hours of service for multiple, interdependent truck drivers to ensure compliance with regulatory resting requirements and service time windows is an extremely challenging task. Models previously designed to schedule truck drivers with...

This paper studies the adoption and diffusion of a product innovation in a duopoly market. Firms are asymmetric, and learning is endogenously determined by the volume of sales. In equilibrium, both high- and low-quality firms may lead adoption, and first-movers are often uniquely determined by...

This paper presents new empirical evidence about the process of plant investment. Using newspaper and trade journal articles, the author collects and analyzes time-to-build data for a sample of Compustat firms. These data suggest that the average construction lead time for new plants is around...

This paper incorporates time-to-build into the standard investment model with convex adjustment costs. The empirical Euler equation is estimated using a U.S. firm-level panel from Compustat. In spite of the introduction of time-to-build, the magnitude of the implied adjustment costs is...

This paper extends the Hartman model to study the optimal rotation age of two interdependent stands when the stream of amenities produced from the two stands may be complements or substitutes, both in space and over time. In the presence of stand interdependence both the ownership structure and...

Endogenous timing can help to derive the time structure of decision making instead of assuming it as exogenously given. In our study we consider a homogeneous market where, like in the model of Kreps and Scheinkman (1983), sellers determine sales capacities before prices. Sellers must serve...

An important element of the cost of distance is time taken in delivering final and intermediate goods. We argue that time costs are qualitatively different from direct monetary costs such as freight charges. The difference arises because of uncertainty. Unsynchronised deliveries can disrupt...

Increased competitiveness with other transport systems and declining operation margins have motivated freight forwarders in the air cargo transport industry to look into horizontal collaboration. This paper focuses on developing a fully integrated five-phase auction-based coopetition model, a...

The aging population and increasing chronic disease load are rapidly changing the face of primary care delivery, with mid-level (e.g., nurse) practitioners providing growing proportion of patient care. Potential differences in the quality of care offered by physicians and nurse practitioners may...
