The goal of this paper is to develop an algebraic theory of process scheduling. We specify a syntax for denoting processes composed of actions with given durations. Subsequently, we propose axioms for transforming any specification term of a scheduling problem into a term of all valid schedules. In particular, we axiomatize an operator that restricts attention to the efficient schedules. These ...

to create values in the working environment and to achieve the organizational aims, organizations have to manage their elements with specific alignment.in principle, different departments of organizations are put together with specific arrangements and tasks in order to create value for the stakeholders .it has been proven that creating value and the outcome of an organization has a direct rela...

data envelopment analysis (dea) is a widely recognized approach for evaluating the efficiencies of decision making units (dmus). because of easy and successful application and case studies, dea has gained much attention and widespread use by business and academy researchers. the conventional dea models (e.g. bcc and ccr) make an assumption that input and output data are exact values on a ratio ...

Green tax reform is unpopular because, typically, the poor are hurt most by higher prices of carbon-intensive commodities. If revenues from a carbon recycled, it may be feasible to gain popular support for green reform. To investigate this, we estimate an EASI demand system German household data and labour supply schedule, using wage data, income schedule let emission intensities decline in tax...

This article will discuss the advantages of planning using such elements organizational and technological documentation as a calendar-network schedule for more efficient process managing production work during implementation an investment construction project.

Abstract- LPP RRI Cirebon in making scheduling is currently not effective and efficient. In addition, broadcast administration still uses general computerization. Thus, for scheduling, the same schedule often occurs at one time causes data loss. This final project will apply software development cycle (SDLC) technique building applications using prototype method. The results of this can help pr...

Exchangeable models for vertex labeled graphs cannot replicate the large sample behaviors of sparsity and power law degree distributions observed in many network datasets. Out of this mathematical impossibility emerges the question of how network data can be modeled in a way that reflects known empirical behaviors and respects basic statistical principles. We address this question by observing ...

In this paper we consider single machine scheduling problems with a common due-date for all jobs, arbitrary monotone earliness and tardiness costs and arbitrary breakdown and repair processes. We show that the problem is equivalent to a deterministic one without breakdowns and repairs and with an equivalent cost function of a job's completion time. A V-shaped schedule without idle times is show...

Canal scheduling is an important activity that significantly influences production of crops compared to other aspects of agriculture. Irrigation canal scheduling is the activity of preparing an optimal schedule of outlets on supply canal as per need of user, subject to canal system constraints. In this paper, the problem of optimal operational scheduling of irrigation canal with provision to op...
