this paper gives a new application of dea to evaluate the scheduling solutions of parallel processing. it evaluates the scheduling solutions of parallel processing using the non-convex dea model, fdh model. by introducing each solution of parallel processing scheduling as a dmu with some relevant inputs and outputs this paper shows that how the most efficient schedule(s) can be identified.
preventive maintenance scheduling of generating units is addressed as a long-term scheduling in power system studies aiming to increase the reliability incorporating cost reduction. it consists of knowing which generating units should be shut down for regular safety inspection. in this paper, a new formulation of preventive maintenance scheduling associated with cost reduction index (cri) is pr...
In the title mol-ecular salt [systematic name: triethylammonium 5-(2,4-dinitrophenyl)-2,6-dioxo-1,2,3,6-tetrahydropyrim-idin-4-olate], C(6)H(16)N(+)·C(10)H(5)N(4)O(7) (-), the cation and anion are linked by an N-H⋯O hydrogen bond. In the crystal, inversion-related barbiturate rings are centrosymmetrically connected through pairs of N-H⋯O hydrogen bonds, forming R(2) (2)(8)R(2) (2)(8) ring motifs.
THE ASYMMETRIC UNIT OF THE TITLE COMPOUND [SYSTEMATIC NAME: 9,10-dimeth-oxy-7-methyl-6,7,7a,8-tetra-hydro-5H-benzo[g][1,3]benzodioxolo[6,5,4-de]quinoline], C(20)H(21)NO(4), contains two independent mol-ecules with very similar bond lengths and angles. The crystal packing exhibits voids of 131 Å(3).
Proper scheduling of tasks leads to optimum using of time and resources, in order to obtaining best result. One of the most important and complicated scheduling problems is open shop scheduling problem. There are n jobs in open shop scheduling problem which should be processed by m machines. Purpose of scheduling open shop problem is attaining to a suitable order of processing jobs by specified...

In this paper, we used the fuzzy set theory for modeling flexible constraints and uncertain data in nurse scheduling problems and proposed a fuzzy linear model for nurse rostering problems. The developed model can produce rosters that satisfy hospital objectives, ward requirements and staff preferences by satisfying their requests as much as possible. Fuzzy sets are used for modeling demands of...
BACKGROUND Nurse staffing interventions have been introduced across countries in recent years in response to changing patient requirements, developments in patient care, and shortages of qualified nursing staff. These include changes in skill mix, grade mix or qualification mix, staffing levels, nursing shifts or nurses' work patterns. Nurse staffing has been closely linked to patient outcomes,...
preventive maintenance scheduling is to perform a series of tasks that prevents or minimizes production breakdowns and improves the reliability. mathematical models have been developed to solve the preventive maintenance scheduling problem. there are several limitations in the prior work in this area of research. craft combinations are assumed to be given. the craft combination problem concerns...
Paper aims Lack of operational planning in healthcare organizations may result service disconnection and reduced value per effort to the patient. Production Planning, Scheduling Control assists determining “what,” “how much,” “when” “where” deliver, which be great relevance services. This study proposes a structural framework analyzes implementation PPSC concepts OR management. Originality The ...
