Time schedule control

The project time schedule control (or planning) system. Generally the same remarks apply as for cost control. Numbering needs are less exacting than for cost control, because roll-ups of like items are not applicable. Generally the numbering systems employed for equipment and documentation are adequate. [Pg.34]

Electromechanical Controls. Electro-mechanical control devices are typically used for load control (lighting, ventilation, and heating) in buildings with no feedback signal. The most common device is the electromechanical timer, in which a small motor coupled to a gearbox is able to switch electrical contacts according to a predefined time schedule. They are still in use today, applied to loads with simple scheduling requirements. [Pg.297]

Multiscale modeling of process operations. The description of process variables at different scales of abstraction implies that one could create models at several scales of time in such a way that these models communicate with each other and thus are inherently consistent with each other. The development of multiscale models is extremely important and constitutes the pivotal issue that must be resolved before the long-sought integration of operational tasks (e.g., planning, scheduling, control) can be placed on a firm foundation. [Pg.267]

The different lubricant suppliers made a technical proposal of their services (technical approach, monitoring, quality of the products, take back lubricants exhaust from the sugar mill, reports on lubricant consumption, environmental benefits like water consumption reduction, energy savings, increase of equipment life-cycles, statistics and controlling) as well as a time schedule for the work plan. Each of the suppliers accepted agreements concluded in a collaboration contract between the Mexican Cleaner Production Centre, the sugar mill and the lubricants supplier. [Pg.85]

The minimum time problem is also known as the time optimal control problem. Coward (1967), Hansen and Jorgensen (1986), Robinson (1970), Mayur et al. (1970), Mayur and Jackson (1971), Mujtaba (1989) and Mujtaba and Macchietto (1992, 1993, 1996, 1998) all minimised the batch time to yield a given amount and composition of distillate using conventional batch distillation columns. The time optimal operation is often desirable when the amount of product and its purity are specified a priori and a reduction in batch time can produce either savings in the operating costs of the column itself or permit improved scheduling of other batch operations elsewhere in a process. Mathematically the problem can be written as ... [Pg.119]

Each process provides capabilities such as meeting production quantity (small to large quantities and/or shapes), performance requirements, proper ratio of reinforcement to matrix, fiber orientation, reliability/ quality control, surface finish, materials used, quantity, tolerance, time schedule, and so forth versus cost (equipment, labor, utilities, etc.). There are products when only one process can be used but there can be applications where different processes can be used. [Pg.474]

The term schedule of reinforcement refers to the nature of the rules governing the allocation of consequences for a particular response. Behavioral performance controlled by a schedule of reinforcement is referred to as schedule-controlled operant behavior. These schedules of reinforcement are critical because they govern the rate and pattern of responding in time which underlie other behavioral functions. For example, the rate of learning may well be influenced by the underlying schedule of reinforcement. If reinforcement of the correct response during... [Pg.235]

The universal measure of schedule-controlled behavior is the rate of responding, which is simply the total number of responses divided by total time. While this is a useful measure of behavior, it provides no indication of other aspects of schedule-controlled behavior, such as the extent of pausing or the patterns of behavior over time. For such purposes, a more fine-grained analysis or microanalysis of performance must be undertaken. [Pg.238]

Another measure of schedule-controlled behavior is that provided by the distribution of the times between successive responses or interresponse times (IRTs). These can be generated as a frequency distribution and have been shown to be important targets of chemical exposure. For example, lead exposure appears to affect primarily the very short IRTs on FI schedules. Many different drugs from a variety of different classes have been shown to increase the frequency of long IRTs and to decrease the frequency of... [Pg.238]

Grouting is but one of many methods of groundwater control used in construction. The choice of a method for any specific job almost always relates back to economics. Factors that contribute to economical selection include the size of the job, the job location, the operation time schedule, and the contractor s capabilities and experience. The problems described below (which were in these specific cases solved by grouting) should not be considered in general as yielding only to grouting techniques, or only to the specific materials that were used in these actual field jobs. [Pg.155]
