abstract

background and objectives: in this paper, a real life nurse scheduling model is described based on the conditions in iranian hospitals such as monthly shift rotation, consecutive morning and evening shifts and consecutive evening and night shift.   methods: the developed model considers both hospital constraints and nurses’ preferences. hospital constraints include assigning adequate qualified number of nurses to all working shifts and avoiding inappropriate sequence of nursing shifts. nurses’ preferences include the nurses’ monthly requests and observing the fairness in ratio of work hours, off weekends, night shifts and undesirable shifts. a hybrid of lexicograph and weighted sum method was used to solve the multi objective problem. the objectives were normalized and the importance of the objectives was determined by the analytical hierarchy process method. in this work, new conditions are considered based on customized considerations. the model was evaluated by comparing the computationally determined schedules with manually determined schedules.   findings: comparison of the manually and computationally determined schedules shows the superiority of computer-based method over the traditionally manual method based on the scales of the hospital.   conclusions: the study provides further support for the utility of sophisticated computational method in improving hospital processes, which can ultimately translate into enhanced patient care and hospital performance.

Discrete-Time Scheduling under Real-Time Constraints

We introduce a new method for scheduling under real-time constraints that is suitable for synchronous system implementations. The input specification is in the form of timing diagrams in which the occurrence times of signal transitions or actions are related by linear constraints, expressing the assumptions on the input actions (the environment) and the commitments on the output actions. Provid...

Real-Time Scheduling Under Time-Interval Constraints

This paper presents a new task model where jobs are divided into segments A, B and C. Segment B has a specific time-interval where it should execute to fulfill some application constraints. We consider the execution of B as valid if performed inside that time-interval, otherwise, its contribution may be valueless to its task. We adapt some scheduling approaches from the literature and present a...

Flexible job shop scheduling under availability constraints

In this paper, an exact geometric algorithm is presented for solving two-job sequencing and scheduling problems in flexible flow shop and job shop environments while the resources are (un)available in some time periods and processors (un)availability is the same in all work centers. This study seems utterly new and it is applicable to any performance measure based on the completion time. The in...

Model-Based Diagnosis under Real-World Constraints

in introducing automated, model-based diagnostic technologies into industrial settings. In particular, I discuss the competition that this technology has been receiving from handcrafted, rule-based diagnostic systems that has set some high standards that must be met by model-based systems before they can be viewed as viable alternatives. The battle between model-based and rulebased approaches t...

Fuzzy portfolio optimization model under real constraints

This paper discusses a multi-objective portfolio optimization problem for practical portfolio selection in fuzzy environment, in which the return rates and the turnover rates are characterized by fuzzy variables. Based on the possibility theory, fuzzy return and liquidity are quantified by possibilistic mean, and market risk and liquidity risk are measured by lower possibilistic semivariance. T...
