A Gantt chart is a type of bar chart [ 4][ 5] that illustrates a project schedule. [ 6] This chart lists the tasks to be performed on the vertical axis, and time intervals on the horizontal axis. [ 4][ 7] The width of the horizontal bars in the graph shows the duration of each activity. [ 7][ 8] Gantt charts illustrate the start and finish ...
Event chain diagram. Event chain diagrams are visualizations that show the relationships between events and tasks and how the events affect each other. Event chain diagrams are introduced as a part of event chain methodology. Event chain methodology is an uncertainty modeling and schedule network analysis technique that is focused on ...
The program evaluation and review technique ( PERT) is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project . PERT was originally developed by Charles E. Clark for the United States Navy in 1958; it is commonly used in conjunction with the Critical Path ...
Automatic lubrication systems (ALS), also known as centralized lubrication systems (CLS), are mechanical devices designed to dispense precise quantities of lubricant to multiple points within machinery during operation. While typically fully automated, some systems may require manual activation via pumps or buttons and still fall under the ...
A needle valve adjusts the rate of flow, which may be seen as drops passing through the window beneath the glass reservoir. A total-loss oiling system is an engine lubrication system whereby oil is introduced into the engine and then either burned or ejected overboard. Now rare in four-stroke engines, total loss oiling is still used in many two ...
The precedence diagram method (PDM) is a tool for scheduling activities in a project plan. It is a method of constructing a project schedule network diagram that uses boxes, referred to as nodes, to represent activities and connects them with arrows that show the dependencies. It is also called the activity-on-node (AON) method. Key elements ...
Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology . Lubrication mechanisms such as fluid-lubricated systems are designed so that the applied load is partially or completely carried by hydrodynamic ...
Example of a more complex EPC diagram (in German). An event-driven process chain ( EPC) is a type of flow chart for business process modeling. EPC can be used to configure enterprise resource planning execution, and for business process improvement. It can be used to control an autonomous workflow instance in work sharing.
