Solutions to the nurse scheduling problem can be applied to constrained scheduling problems in other fields. [2] [3] While research on computer-assisted employee scheduling goes back to the 1950s, [4] the nurse scheduling problem in its current form was introduced in two parallel publications in 1976. [5] [6] It is known to have NP-hard ...
Optimal job scheduling is a class of optimization problems related to scheduling. The inputs to such problems are a list of jobs (also called processes or tasks) and a list of machines (also called processors or workers). The required output is a schedule – an assignment of jobs to machines. The schedule should optimize a certain objective ...
Project Cost Management (PCM) is the dimension of project management which aims to ensure that a project is completed within its approved budget. [1] [2] It encompasses several specific project management activities including estimating, job controls, field data collection, scheduling, accounting and design, and uses technology to measure cost and productivity through the full life-cycle of ...
Cost engineering is "the engineering practice devoted to the management of project cost, involving such activities as estimating, cost control, cost forecasting, investment appraisal and risk analysis". [1] "Cost Engineers budget, plan and monitor investment projects.
Positive slack would indicate ahead of schedule; negative slack would indicate behind schedule; and zero slack would indicate on schedule. critical path: the longest possible continuous pathway taken from the initial event to the terminal event. It determines the total calendar time required for the project; and, therefore, any time delays ...

The objective of the stochastic scheduling problems can be regular objectives such as minimizing the total flowtime, the makespan, or the total tardiness cost of missing the due dates; or can be irregular objectives such as minimizing both earliness and tardiness costs of completing the jobs, or the total cost of scheduling tasks under likely arrival of a disastrous event such as a severe typhoon.
Tools used in cost are, risk management, cost contingency, cost escalation, and indirect costs. But beyond this basic accounting approach to fixed and variable costs, the economic cost that must be considered includes worker skill and productivity which is calculated using various project cost estimate tools.
