The problem of dispatching shuttles to serve trip requests can be mathematically formulated as a dial-a-ride problem (DARP). With on-demand mobility services gaining more popularity due to the recent developments in gig economy, communication technologies, and urbanization, the real-time...

This paper presents new formulations for multi-activity shift scheduling problems (MASSP). In these formulations, the rules governing the feasibility of shifts are encoded in state-expanded networks in which nodes are associated with states and arcs represent assignments inducing state...

For promising outcome in industry 4.0, scheduling place a vital role for effective utilization of jobs allocate to machine. Job’s and machine’s are two attributes need to schedule for minimize makespan time, for each job we need to schedule the machine. Each job in a machine has its own...

In this paper Sensitivity & Optimal Design of a Bi-Directional Mechanical Machine with Modulated Double Flow is proposed. Aim is control the inward rotor position with a little servo engine and with the bi-directional motion regulation impact, the resultant instigated voltages in two...

The paper studies institutional trading ahead of scheduled information releases, notably earnings announcements. While scheduled news are known to be preceded by sizeable stock returns, we find that institutional investors on average forego part of these premia as they decrease their exposure to...

CPU scheduling is one of the most crucial operations performed by operating systems. Different conventional algorithms like FCFS, SJF, Priority, and RR (Round Robin) are available for CPU Scheduling. The effectiveness of Priority and Round Robin scheduling algorithm completely depends on...

It has long been observed that model structure may play an important role in determining the effectiveness of certain solution techniques to mixed integer linear programs (MILPs). One implication is that solution techniques that work well for one class of MILP are often found to be effective on...

We study an integrated airline schedule design and fleet assignment model for constructing schedules by simultaneously selecting from a pool of optional flights and assigning fleet types to these scheduled flights. This is a crucial tactical decision which greatly influences airline profit. As...

Prediction helps organizations in their decision-making activities for the improvement of the different functions, services, and even their income. The C4.5 algorithm is the most commonly used prediction algorithm having difficulty in choosing attributes that lead to low prediction accuracy....
