USE

The duration of an event is used by numerous other functionalities in VISUAL PLANNING.

Impact on other functionalities

Load

The load of an event can be determined as a function of the duration, in the event that the load type is:

  • Automatic,

  • in days, by day,

  • in hours by day,

  • In days by hour,

  • In hours by hour,

  • As a percentage.

Example:

An event, with a duration of 2 days, has a load of 2 days per day.

The value of the load is therefore 4 days.

Valuation items

The valuation variable for an event is determined from the duration, if the time unit for the valuation item is:

  • the day,

  • the hour,

  • the load, in days (if the type of load is variable with the duration),

  • the load, in hours (if the type of load is variable with the duration),

  • Depending on the type of event.

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

An event, with a duration of 2 days, has a valuation variable with a value of 2.

The total value of the valuation item is therefore 4.

Example 2: The time unit for the valuation item is the load, in days.

An event, with a duration of 2 days, has a load of 2 days per day.

The value of the load is therefore 4 days.

This event has a valuation variable with a value of 2.

The total value of the valuation item is therefore 8.

Calculations for events durations

Control total type section

A Control Total type heading is used to produce a total of the durations of multiple events.

This duration can be:

  • Duration of events (h): The total of the duration for events converted into hours. If the events are in hours, this is simply the total of the durations of these events.

  • Duration of events (d): The total of the duration for events converted into days. If the events are in days, this is simply the total of the durations of these events.

  • Achieved duration (h): The total of the completed duration of events, converted into hours.

  • Achieved duration (d): The total of the completed duration of events, converted into days.

  • Duration of free periods (h): These are the free periods in the planning, converted into hours.

  • Duration of free periods (d): These are the free periods in the planning, converted into days.

  • Occupation duration (h): The period during which the resource is occupied, in hours. This duration is calculated using the coverage, or not, of the free periods, and may not exceed the total of the latter.

  • Occupation duration (d): The period during which the resource is occupied, in days. This duration is calculated using the coverage, or not, of the free periods, and may not exceed the total of the latter.

See conversion of days into hours

Example:

A resource with a daily calendar, when only Saturdays and Sundays are not worked. In addition it has an hourly calendar, with 8 hours worked per day.

Within this resource an event exists during the week. It starts on the Monday and ends the next Thursday. This event is completed to a level of 50%.

The duration, in days, of the event is therefore 4 days. The duration, in hours, is 32 hours.

Its completed duration in days is therefore 2 days. Its completed duration in hours is therefore 16 hours.

The duration of the free periods in days during the week, is 1 day. The duration of the free periods in hours, is 8 hours.

load

A workload is used to provide a total of the durations of multiple events for the whole of a time period.

Each of these periods is linked to the time scale on a planning view, which is used to visualize the load.

This duration can be:

  • Duration of events (h): The total of the duration for events converted into hours. If the events are in hours, this is simply the total of the durations of these events.

  • Duration of events (d): The total of the duration for events converted into days. If the events are in days, this is simply the total of the durations of these events.

  • Occupation duration (h): The period during which the resource is occupied, in hours. This duration is calculated using the coverage, or not, of the free periods, and may not exceed the total of the latter.

  • Occupation duration (d): The period during which the resource is occupied, in days. This duration is calculated using the coverage, or not, of the free periods, and may not exceed the total of the latter.

  • Duration of free periods (h): These are the free periods in the planning, converted into hours.

  • Duration of free periods (d): These are the free periods in the planning, converted into days.

Example:

An event starts on the Monday and ends the next Tuesday.

A load, calculating the duration in days, is shown on the daily time scale.

The value of the load is equal to 1 day on Monday and 1 day on Tuesday.

Events Report

This duration can be:

  • Duration of events (h): The total of the duration for events converted into hours. If the events are in hours, this is simply the total of the durations of these events.

  • Duration of events (d): The total of the duration for events converted into days. If the events are in days, this is simply the total of the durations of these events.

  • Achieved duration (h): The total of the completed duration of events, converted into hours.

  • Achieved duration (d): The total of the completed duration of events, converted into days.

  • Duration of free periods (h): These are the free periods in the planning, converted into hours.

  • Duration of free periods (d): These are the free periods in the planning, converted into days.

Events values heading

An events value type heading is used to assign the duration of an event to a resource.

This duration can be:

  • Duration in hours: This is the duration of the event, if in an hourly format; or a conversion into hours if it is daily format.

  • Duration in days: This is the duration of the event, if in an daily format; or a conversion into days if it is hourly format.

Operation type heading.

An operations type heading, in duration mode, is used to calculated a duration as being the difference between two dates, sourced from two headings, of the type:

  • Date/hour,

  • or event value.

Example:

This heading is used to establish a calculated duration as being the difference between the end date of an event and the start date of another.

Conversion of days into hours

A duration may be converted into a number of hours or a number of days.

Example:

A daily-counted event lasts 3 days, the calendar for the event indicates that each day lasts 8 hours.

The conversion into days, of the daily duration of this event, returns the value of 24 hours.
