VISUAL PLANNING 5.3 DOCUMENTATION

Duration

DEFINITION

The duration allows to quantify the time, attributing it a number and a unit.

Depending on the entity type handling in VISUAL PLANNING, the time units can be:

  • The day.
  • The half-day.
  • The hour.
  • The minute.

The main duration used by VISUAL PLANNING is the event that results from the difference between:

  • The end date/hour of the event.
  • The start date/hour of the event.

This duration may be added, converted, and used by different features.

The maximum duration of an event is 20000 days.

SETTINGS

The settings are to initialize the duration of an event.

Events creation rules

Events creation rules are at the origin of event duration.

The default duration drives the creation. It can be:

  • Undefined.
  • According to the heading.
  • Fixed value.
  • The result of an operation between two headings.
  • According to a resource's calendar.

Creation rules also determine if the event is worked or not. It is an important factor to get the end date/hour of the event depending on his duration. To get the event duration depending on his end date/hour (case of the import events).

Calendars

Hourly and daily calendars are an other parameter to determine the event duration but it has to be worked. Unworked periods are not included int the duration of a worked event. (cf. Hourly calendar and daily calendar)

Example:

The event follows a daily calendar on which Saturday and Sunday are unworked.

This event starts on Friday, ends on Monday. Its duration will be:

  • Event worked: 2 days
  • Event unworked: 4 days

USE

The duration of an event is used by many other features of VISUAL PLANNING.

Initializing other features

Load

The event load is determined by the following type of load:

  • Automatic.
  • In days per day.
  • In Hours per day.
  • In Hours per hour.
  • In percentage.

Example:

A two days event duration has a load of 2 days per day.

cf. Load

Valuation items

The variable value of an event is determined by the duration of it, if the time unit of the valuation item:

  • The day.
  • The hour.
  • The load in day (if the type of load varies depending on the duration).
  • The load in hour (if the type of load varies depending on the duration).
  • The type of the event.

Example 1: The time unit of the valuation item is the day.

A 2 days event has a variable valuation of 2.

The total value of the valuation item is then 4.

Example 2: The time unit of the valuation item is the load in day.

A 2 days event has a load of 2 days per days.

The load value is then 4 days.

This event has a variable value of 2.

The total valuation item is then 8.

Calculation on the event duration

Control column heading

A control column heading permits to sum the duration of several events.

This duration can be:

  • Events duration (h): this is the sum of the events duration convert in hours.If If the events are hourly, it is simply the sum of these event duration.
  • Events duration (d): this is the sum of the events duration convert in days.If If the events are daily, it is simply the sum of these event duration.
  • Completed duration (h): this is the amount realized from the duration amount achievement of events converted to hours.
  • Completed duration (d): this is the amount realized from the duration amount achievement of events converted to days.
  • Free period duration (h): this is the schedule's free period convert to hours.
  • Free period duration (d): this is the schedule's free period converted to days.
  • Occupation duration (h): This is the resource's occupation period converted to hours. This duration is calculated by the recovery or non recovery of free periods and may not exceed the sum of these.
  • Occupation duration (d): This is the resource's occupation period converted to days. This duration is calculated by the recovery or non recovery of free periods and may not exceed the sum of these.

c.f Converting days to hours

Example:

A resource has a daily calendar which only Saturday and Sunday are not worked. It possesses a calendar schedule with 8 hours worked every day.

On this resource, an event is planned during the week. It starts Sunday and ends next Thursday. The achievement of this event is 50%.

The duration in days of the event is then 4 days. His duration in hours is 32 hours.

His achievement duration in days is then 2 days. His achievement duration in hours is 16 hours.

The free period duration in days on the week is 1 day. The free period duration in hours is 8 hours.

Workload

A workload permits to sum the duration of several events on periods.

Each period is linked to a schedule view which is used to visualize the workload. This duration can be:

  • Events duration (h): this is the sum of the events duration convert in hours.If If the events are hourly, it is simply the sum of these event duration.
  • Events duration (d): this is the sum of the events duration convert in days.If If the events are daily, it is simply the sum of these event duration.
  • Completed duration (h): this is the amount realized from the duration amount achievement of events converted to hours.
  • Completed duration (d): this is the amount realized from the duration amount achievement of events converted to days.
  • Free period duration (h): this is the schedule's free period convert to hours.
  • Free period duration (d): this is the schedule's free period converted to days.

Example:

An event starts Monday and ends on Tuesday.

Workload calculate the duration in days is visualized on a daily scale.

The workload value is equal to 1 day on Monday and 1 on Tuesday.

Events report

An events report allows to sum duration of several events.

This duration can be:

  • Events duration (h): this is the sum of the events duration convert in hours.If If the events are hourly, it is simply the sum of these event duration.
  • Events duration (d): this is the sum of the events duration convert in days.If If the events are daily, it is simply the sum of these event duration.
  • Completed duration (h): this is the amount realized from the duration amount achievement of events converted to hours.
  • Completed duration (d): this is the amount realized from the duration amount achievement of events converted to days.
  • Free period duration (h): this is the schedule's free period convert to hours.
  • Free period duration (d): this is the schedule's free period converted to days.
  • Occupation duration (h): This is the resource's occupation period converted to hours. This duration is calculated by the recovery or non recovery of free periods and may not exceed the sum of these.
  • Occupation duration (d): This is the resource's occupation period converted to days. This duration is calculated by the recovery or non recovery of free periods and may not exceed the sum of these.

Event value heading

A heading of this type is used to assign a resource to the duration of an event.

This duration can be:

  • Duration in hours: this is the event duration. If his type is hourly, or the conversion is in hours, his type is hourly.
  • Duration in days: this is the event duration. If his type is daily, or the conversion is in days, his type is daily.

Operation heading

A heading of this type, in duration mode, allows to calculate a duration. This duration is the difference between two dates that come from two type of headings:

  • Date/hour.
  • Event value.

Example:

This heading permits to establish a calculated duration as the difference between an event ending date and the start date of an other event.

Converting days into hours

A duration can be convert into a number of days/hours.

Example:

A 3 days event duration. The calendar is 8 hours a day.

The duration in days for this event gives as a result a value of 24 hours.
