Automatic scheduling

Scheduling of work tasks and therefore labor utilization can be carried out in a number of different methods on a computer, depending on the software system purchased. These methods can be similar to the manual system or they may take the form of automatic scheduling. That is, the work tasks are entered into the computer system with the appropriate hours and trades and the software program automatically schedules the hours evenly over the weeks of the year. In implementing such scheduling care has to be taken to ensure that such items as weekends, statutory holidays, annual leave, annual shutdown and seasonal...

Enhanced preventive and predictive mainterumce PMlPdM) Automatic scheduling of repetitive PM activities is possible through CMMS. PM tasks and inspection frequencies can be documented on the PM module and printed as part of the PM work order. A CMMS enhances PM by providing a method to monitor failure trends and highlight major causes of equipment breakdowns and unscheduled repairs. 

Opens and edits work orders and automatically schedules and records when jobs are completed. Jobs done under PM usually include inspections, lubrications, and changes of finite-lifetime items such as filters or seals. 

Note that the schedule of Figure 15.12 was generated using the Automatic scheduling mode of SchedulePro that attempts to schedule a multi-batch campaign based on a fixed cycle time (the minimum by default). Solutions based on other scheduling modes (e.g., the ASAP mode) are displayed in the sections that follow. 

Whereas issues of technician productivity, sample status, and scheduling of analyses are economically important, these take second place to the issue of measurement quaUty in the laboratory. LIMS software enables activities such as cahbration and proper maintenance to be scheduled automatically. By recording the results of these activities in the LIMS, the data to demonstrate proper performance are readily made available. Additionally, the schedule can be adjusted to reflect the actual needs of the individual instmments. 

With the advance of the turbine to idle speed, the turbine is ready to synchronize, and control is considered in synchronization. Both manual and automatic synchronizing are available locally. The unit is synchronized, and the main breaker closed. The speed reference will be switched to become a load reference. The speed/load reference will be automatically increased at a predetermined rate so that the fuel valve will be at the approximate position required for the desired load. For maintenance scheduling, the computer will count the number of normal starts and accumulate the number of hours at the various load levels. 

Air cleaning (dust collection) can be cost effective for LVHV systems handling valuable dusts. Care must be taken when handling potentially toxic dusts from air cleaners. Regular, routine reconditioning of fabric filters (e.g., by automatic shaking or pneumatic pulsing) is impottant. This can be accomplished on a set maintenance schedule or as a function of pressure drop across the fabric filter. It is not recommended to recirculate airflow back to the workplace because of the low air volume and potential hazards in the event of filter failures.

Another important specific question to ask is how the software schedules patient visits. Does it schedule all visits when a patient is enrolled in the study, or is this done at specific phases (event) For example, first, screening visits are scheduled, and then follow-up visits are scheduled after the patient is randomized. Related to this is how the software handles event-driven visits. For example, if a specific event occurs, additional visits at predefined intervals from the date of the event are expected. So the question here is whether the software can be configured to schedule these additional visits automatically as protocol visits or the user needs to schedule them as interim visits. 

An adaptive control system can automatically modify its behaviour according to the changes in the system dynamics and disturbances. They are applied especially to systems with non-linear and unsteady characteristics. There are a number of actual adaptive control systems. Programmed or scheduled adaptive control uses an auxiliary measured variable to identify different process phases for which the control parameters can be either programmed or scheduled. The "best" values of these parameters for each process state must be known a priori. Sometimes adaptive controllers are used to optimise two or more process outputs, by measuring the outputs and fitting the data with empirical functions. 

EPA incorporated them directly into the regulations. HSWA is all the more significant because of the ambitious schedules that Congress established for implementation of the Act s provisions. Another unique aspect of HSWA is that it established statutory requirements that would go into effect automatically (with the force of regulations) if U.S. EPA failed to issue regulations by certain dates.

Once a test 1s complete, another menu option provides the data analysis results 1n the form of a hard-copy report printed on the local line printer. The report Includes experiment identification Information and the apparent viscosities calculated for each data set. A subset of the data analysis program 1s scheduled automatically by the control programs while the experiment is 1n progress and provides immediate on-line analysis of apparent viscosities for each data set as It 1s collected. The results are viewed using the real-time data display program (Figure 5). 

This assignment of basic operations to the technical functions of vessels and stations and to AGVs can be computed automatically by a scheduling algorithm during a simulation run. 

The start time of all batches was set to 7 00 AM. For all scenarios evaluated, the sequencing and the resource allocation were done automatically by the scheduling algorithm.

Planned orders and other information are sent from the ERP system to a scheduling system via an interface. The scheduling system has its own database and a number of different automatic and interactive scheduling functions. Scheduling results are sent back to the superior system via an interface at the end of the scheduling process. This loose integration respects the hierarchical concept and the autonomy of the planners. 

Some load shedders use a demand target that is not fixed but increases at a steady rate. Other devices allow the off-on setpoints to be adjusted independently for individual loads. Loads can be cycled based on the maximum demand target, time of day and day or week, rate of demand increase, heating and cooling temperatures, pressures, fuel flow and rates, occupancy schedules, inside and outside temperatures, humidity, wind direction and velocity and combinations of the above factors. Durations can be variable and changed automatically according to these parameters. 

However, the main reason for the lack of wide application of on-line adaptive control is the lack of economic incentive. On-line identification is rarely required because it is usually possible to predict with off-line tests how the controller must be retuned as conditions vary. The dynamics of the process are determined at different operating conditions, and appropriate controller settings are determined for all the different conditions. Then, when the process moves from one operating region to another, the controller settings are automatically changed. This is called openloop-adaptive control or atn scheduling.
