The schedule or schedule , as a basic time management tool, consists of a timetable where possible tasks, events, or actions are intended to be performed, or from a sequence of events in chronological order where such things are meant to happen. The schedule-making process - deciding how to order these tasks and how to do resources between possible tasks - called scheduling , and the person responsible for creating a specific schedule can be called scheduler . Creating and following a schedule is an activity of early humans.
Some scenarios associate this "planning" by learning "life skills". Schedule is necessary, or at least useful, in situations where individuals need to know what time they should be in a particular location to receive a particular service, and where people need to achieve a set of goals within a certain timeframe.
Schedules can be useful for both short periods, such as daily or weekly schedules, and long-term planning with regard to periods of several months or years. They are often created using a calendar, where the person making the schedule can record the date and time in which events are planned. Schedule that does not specify a specific time for events to occur can instead register algorithmically the expected sequence in which events can or should occur.
In some situations, schedules can be uncertain, such as where the behavior of everyday life depends on environmental factors outside of human control. People who are on vacation or trying to reduce stress and achieve relaxation can deliberately avoid schedules for a certain period of time.

Schedule type
Schedule is publicly available
Some types of schedules reflect information that is generally available to the public, so that community members can plan specific activities around them. This may include things like:
- Business operating hours, tourist attractions, and government offices, allowing consumers to know when they can get it.
- Transportation schedules, such as flight schedules, train schedules, bus schedules, and various public transport schedules are published to allow commuters to plan their trips. From the perspective of the organization responsible for providing transportation, the schedule should provide the possibility of schedule delays, the term in transportation modeling that refers to the difference between the desired arrival or departure time and the actual time. Although using "delays", it can refer to differences in either the initial or final directions.
- In broadcast programming, minute planning of radio or television broadcasting content, the result of such activities is the creation of a list of events to be broadcasted on a regular time or at a specified time, which is then distributed to the public so that a potential audience for the show will know when it will available to them.
- Concerts and sporting events are usually scheduled so fans can plan to buy tickets and attend events.
Internal schedule
Internal timetables are schedules that are only important for people who must obey them immediately. It has been noted that "groups often begin with an imposed schedule from the outside, but effective groups also develop an internal schedule that sets goals for the completion of micro tasks". Unlike schedules for public events or public facilities available, there is no need to go into time and effort to publish internal schedules. Conversely, internal schedules can be kept confidential as security or propriety issues.
Examples of internal schedules are workplace schedules, which include the hours that certain employees expect in the workplace, ensuring sufficient staffing at all times while in some cases avoiding staff surplus. Work schedules for businesses that are open to the public must be in accordance with business hours of operation, so that employees are available when customers can use business services. One common method of scheduling employees to ensure the availability of appropriate resources is the Gantt chart. Another example of an internal schedule is a student's class schedule, which shows what day and time their class will be held.
Project management scheduling
The schedule may also involve the completion of projects that the public has no public interaction before its completion. In project management, formal schedules are often made as a first step in implementing specific projects, such as building construction, product development, or program launch. Establishing a project management schedule involves a list of milestones, activities, and deliveries with expected start and end dates, which employee scheduling can be an element. Production process schedules are used for production or operation planning, while resource schedules assist in logistics planning for resource sharing among multiple entities.
In such cases, the schedule "is obtained by estimating the duration of each task and recording any dependencies between tasks". Dependencies, in turn, are tasks to be accomplished to enable other tasks, such as renting a truck before loading material in the truck (since nothing can be loaded until the truck is available for things to load). Project scheduling, therefore, requires the identification of all the tasks required to complete the project, and the earliest time at which each task can be completed. In making a schedule, a certain amount of time is usually set aside as possible against unexpected days. This time it is called variance scheduling, or float, and is the core concept for the critical path method.
In computing
Scheduling is important as an internal process in computer science, where schedules are a list of actions from a series of transactions in a database, and scheduling is the way multiple processes are assigned in computer multitasking and multiprocessed operating system design. Such scheduling is incorporated into computer programs, and users may be completely unaware of what tasks are being performed and when. Operation scheduling and computing issues may include:
- The operation of the network scheduler or packet scheduler, the arbitrator program that manages the movement of certain pieces of information on the computer.
- Open-shop scheduling, Job Shop scheduling, Flow Shop Scheduling Issues, optimization problems in computer science.
- I/O scheduling, the order in which I/O requests are sent to the block device in the operating system.
- Job scheduler, enterprise software application responsible for unattended background execution.
In wireless communication
Wireless networks should have a flexible service architecture to integrate different types of services on a single air interface because the terminals have different service requirements. Above a flexible service architecture, an effective Quality of Service (QoS) management scheme is also required. Therefore, wireless resources must be shared among all terminals carefully and it is expected to schedule the efficient use of wireless resources as efficiently as possible while maximizing overall network performance.
In operations research
Resource scheduling, usually subject to constraints, is the subject of some of the existing problems in the field of research known as operations research, usually in terms of finding an optimal solution or method of completion.
For example, the nurse scheduling issue is related to scheduling a number of employees with typical constraints such as shift rotation, overtime limits, etc. The problem of traveling salesmen is related to scheduling a series of trips to minimize time or distance. Some of these problems can be solved efficiently with linear programming, but many scheduling problems require integer variables. Although efficient algorithms exist to provide integer solutions in some situations (see network stream model), most problems that require integer solutions have not been resolved efficiently.
In Transport Planning
One of the areas that scheduling can be very useful is Transport Planning. An example, continue to build a highway in your mind; Important components of a transport improvement proposal include (a) a thorough evaluation of the scope of work to be completed, (b) a sufficiently accurate cost estimate to complete the task, and (c) a feasible project schedule. If any of these factors are not accurately defined, then there is a strong possibility of unforeseen difficulty. Bad scoping and/or scheduling can lead to serious budgetary problems, delays and cancellation of transport improvements, and sometimes even domino effects that could negatively impact transport planning across the region.
