Preventive maintenance is the essential part of many maintenance plans. From the production point of view, the flexibility of the maintenance intervals enhances the manufacturing efficiency. On the contrary, the maintenance departments tend to know the timing of the long term maintenance plans as certain as possible. In a single-machine production environment, this paper proposes a simulation–o...

The hydration of fat free mass (FFM) and extracellular (ECW) and intracellular water (ICW) compartments were studied in 30 obese premenopausal women before and after a 3-mo weight-reduction program and again after a 9-mo weight-maintenance program. Body fat was determined by a four-compartment model. Total body water and ECW were determined by deuterium dilution and bromide dilution, respective...

Background: Acquired immune deficiency syndrome (AIDS) is one of the greatest social health problems in many communities in the twenty-first century. Methadone maintenance treatment (MMT) could decrease HIV infection among injection drug users (IDU). The main aim of this paper was to determine the cost-effectiveness of the governmental MMT program to prevent human immunodeficiency virus (HIV) i...

A joint optimization model of maintenance and operation high-speed train fleets is established with the objective minimizing total costs, considering dynamic passenger flow resources. new strategy CCPM (Coordinating Conflicts Preventive Maintenance) proposed to optimize problem. The effectiveness are verified by numerical examples. comparison between in paper existing approach proves that more ...

BACKGROUND Weight lost by obese patients is almost always regained over time. Extended treatment may improve maintenance, but solid evidence is lacking. PURPOSE We determined effectiveness of maintenance therapy after a weight loss program. METHODS Together 201 patients (mean age 47 years and BMI 42 kg/m(2), 71% women) were randomly assigned to either a 17-week weight loss program followed ...

a few years after the implementation of computerize maintenance management systems (cmms), showing the analysis results of the collected data in these systems is necessary and important for continuing the usage of these systems. equipment downtime and cost data can identify patterns of equipment faults and equipment costs. it can also show deficiencies in the implementation of maintenance syste...

A key aspect of lean manufacturing practices is the implementation of an integrative total productive maintenance (TPM) system. Manufacturers and others implementing lean practices need to understand the importance of employee involvement and support of an integrative TPM approach. The paper summarizes key aspects in the literature associated with team based and union environment that support a...
