History of PDF. The Portable Document Format (PDF) was created by Adobe Systems, introduced at the Windows and OS/2 Conference in January 1993 and remained a proprietary format until it was released as an open standard in 2008. Since then, it has been under the control of an International Organization for Standardization (ISO) committee of ...
The 4–4–5 calendar is a method of managing accounting periods, and is a common calendar structure for some industries such as retail and manufacturing. It divides a year into four quarters of 13 weeks, each grouped into two 4-week "months" and one 5-week "month". The longer "month" may be set as the first (5–4–4), second (4–5–4), or ...
A master production schedule (MPS) is a plan for individual commodities to be produced in each time period such as production, staffing, inventory, etc. [1] It is usually linked to manufacturing where the plan indicates when and how much of each product will be demanded. [2] This plan quantifies significant processes, parts, and other resources ...
3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
Material requirements planning. Material requirements planning (MRP) is a production planning, scheduling, and inventory control system used to manage manufacturing processes. Most MRP systems are software -based, but it is possible to conduct MRP by hand as well. An MRP system is intended to simultaneously meet three objectives:
Electronic data interchange (EDI) is the concept of businesses electronically communicating information that was traditionally communicated on paper, such as purchase orders, advance ship notices, and invoices. Technical standards for EDI exist to facilitate parties transacting such instruments without having to make special arrangements.
3D model slicing. Rapid prototyping is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design (CAD) data. [1][2] Construction of the part or assembly is usually done using 3D printing or "additive layer manufacturing" technology. [3]
