Abstract:

OASIS PPS (Production Planning and Scheduling) specifications deal with problems of decision-making in all manufacturing companies who want to have a sophisticated information system for production planning and scheduling. PPS specifications provide XML schema and communication protocols for information exchange among manufacturing application programs in the web-services environment. Part 1: Core Element especially focuses on information model of core elements which can be used as ontology in the production planning and scheduling domain. Since the elements have been designed without particular contexts in planning and scheduling, they can be used in any specific type of messages as a building block depending on the context of application programs.

1      Introduction

This document prescribes how to describe contents of the XML messages which are used for exchanging the information on Production Planning and Scheduling by some application software programs.

If information is exchanged between production planning and scheduling applications, the enterprise can develop systems comparatively easily at a low cost and make them more competitive for the whole enterprise.  To make matters better, the systems will be able to have high extendability in future.

This specification aims at production planning and scheduling for all kinds of products and services provided by manufacturing enterprises.  Production scheduling explained in this specification can be divided into scheduling in the whole enterprise including some areas and sites, and detailed scheduling within an individual area and work-centers.

The scope of this specification doesn’t include optimization logic for solution, special knowledge of individual enterprises, concrete solution methods for production planning and scheduling, and planning for the total supply chain.

1.4 Terms and definitions

Plan

Unit for intensive information of related orders corresponding to a specific period on a discrete time scale, or calculated information based on the schedule under the related orders.  This can represent actual results when the related events have been occurred.

Order

Unit of requirement describing concrete item, resource or operation in a specific place at a specific time.  This can also represent the results to the requirement.

Party

Customer who is a sender of an order and has a demand to make a decision, or supplier who is a receiver in case that a decision-maker sends the demand that can’t be handled inside.

Item

Object to be produced or consumed by production activities.  The quantity or the quality of item is changed during the production activity. Examples include product, parts, module, unit, work in process and materials.

Resource

Object that can provide essential function for production activities.  The capacity of function is used during production activity, and is available again after finishing the production. Examples include equipment, machine, device, labor and tool.

Process

Segment of production activities indicating a certain production line or method.  This takes duration from start time to end time, and gives added value to the producing item.  One process may have two or more than two processes detailed in the lower levels.

Lot

Instance of a specific volume of item that exists in a specific place at a specific time.  Generally the specific time corresponds to start or end of an operation, and the specific volume is equal to the quantity of item produced or consumed by the operation.

Task

Unit of necessity to execute a specific operation at a specific time, indicating the volume of used capability provided by the applicable resource. This can represent both capacity value provided by resource at a specific time point, and aggregated total value of capacity provided by resource during specific duration.

Operation

Actual processing element to be executed by a specific task, and to produce or consume a specific lot.  It is a concrete instance of particular processes in production activities.

2.2 List of primitive elements

This specification defines nine primitive elements: Party, Plan, Order, Item, Resource, Process, Lot, Task, and Operation. The type of those elements SHOULD be represented with the following XML schema.

 

  <xsd:element name="Party" type="PrimitiveType"/>

  <xsd:element name="Plan" type="PrimitiveType"/>

  <xsd:element name="Order" type="PrimitiveType"/>

  <xsd:element name="Item" type="PrimitiveType"/>

  <xsd:element name="Lot" type="PrimitiveType"/>

  <xsd:element name="Task" type="PrimitiveType"/>

  <xsd:element name="Operation" type="PrimitiveType"/>

 

2.2.1 Party element

Party element represents a customer or a supplier. Customer is an object that requests some products or services to the enterprise.  The requests are sent to a person who is in charge of production planning and scheduling.  Supplier is an object providing some products or services to the enterprise.  Supplier receives orders form the enterprise, and provides corresponding items, resources or processes for the enterprise.

2.2.2 Plan element

Plan element represents a value planned for particular products or services. The value shows volume of the products or services required or resulted during certain period of time. Typical cases of planning period  include day, week and month.

2.2.3 Order element

Order element represents an object of information produced to request some products or services.  Order is source to create production orders that are finally dispatched to the plant floor.  Orders can be divided into inventory order, capacity order and production order according to the type of request. 

 

Example: Ten “A” products are requested.

<Order id=”Z01” item=”A”>

  <Spec type=”quantity”><Qty value=”10”/></Spec>

</Order>

Example: Three labors in group “B” are requested.

<Order id=”Z02” resource=”groupB”>

  <Spec type=”quantity”><Qty value=”3”/></Spec>

</Order>

Example: Switching operation is requested two times.

<Order id=”Z03” process=”change01”>

  <Spec type=”quantity”><Qty value=”2”/></Spec>

</Order>

Example:  Order which consist of 10 of “A” and 5 of “B” is totally 3,000 yen.

<Order id=”Z00”>

  <Compose order=”Z01”/>

  <Compose order=”Z02”/>

  <Price value=”3000” unit=”yen”/>

</Order>

<Order id=”Z01” item=”A”>

  <Spec type=”quantity”><Qty value=”10”/></Spec>

</Order>

<Order id=”Z02” item=”B”>

  <Spec type=”quantity”><Qty value=”5”/></Spec>

</Order>

 

2.2.4 Item element

Item element represents a product, component, parts, work in process (WIP), raw material and other items.  Item is produced by any processes, and after that, it is consumed by another processes.  Lot is an instance of the corresponding item.

2.2.5 Resource element

Resource element represents a resource, which is an object enabling production, transportation, storage, inspection and other various services.  As resource can produce tasks to execute operations, it  is assigned to an operation by considering its volume of capacity.

2.2.6 Process element

Process element represents a process that has a function to produce value.  Process can be defined as a segment of activities in production process. It produces and consumes production items by being executed during certain period of time.

2.2.7 Lot element

Lot element represents a production lot.  Production lot is an object corresponding to a concrete item that actually exists in a specific place at a specific date and time.  Lot is produced by an operation and finally consumed by another operation or discarded. 

2.2.8 Task element

Task element represents a task, which is an object showing the usage of a specific resource capability for a specific period of time.  Schedule may request a certain volume of task for each resource assigned to execute the appropriate operations. 

 

Example: Task corresponding to the volume that 3 labors work load is required for 2 days

<Task id=”T01”>

  <Capacity type=”human”><Qty value=”3”/></Capacity>

  <Capacity type=”duration”><Qty value=”2” unit=”day” /></Capacity> 

</Task>

 

2.2.9 Operation element

Operation element represents a segment of activities that is actually dispatched to plant floor.  Operation identifies an executable function at a specific place on a plant floor for a specific time.  Operation is associated with a specific lot and task by executing those activities.

3.2 List of relational elements

This part of specifications defines five relational elements: Compose, Produce, Consume, Assign, and Relation. Relational element defines relationship between the parent element and those that characterize the element. The type of this element SHOULD be represented with the following XML schema.

 

  <xsd:element name="Compose" type="RelationalType"/>

  <xsd:element name="Produce" type="RelationalType"/>

  <xsd:element name="Consume" type="RelationalType"/>

  <xsd:element name="Assign" type="RelationalType"/>

  <xsd:element name="Relation" type="RelationalType"/>

 

3.2.1 Compose element

Compose element defines a hierarchical relation between the parent element and another same primitive element that addresses one level upper or lower than the target element.  This element can represent that the object referred to in this element composes or be composed by the parent element.

 

Example: Product “A” family includes product “A1” and product “A2”.

<Item id=”A”>

  <Compose type=”child” item=”A1”/>

  <Compose type=”child” item=”A2”/>

</Item>

Example: Product “B” is assembled with 2 of parts “C1” and 3 of parts “C2”.

<Item id=”B”>

  <Compose type=”child” item=”C1”><Qty value=”2”/></Compose>

  <Compose type=”child” item=”C2”><Qty value=”3”/></Compose>

</Item>

Example: 2 of parts “C1” are used for product “B1”, and 5 of parts “C1” are used for product “B2”.

<Item id=”C1”>

  <Compose type=”parent” item=”B1”><Qty value=”2”/></Compose>

  <Compose type=”parent” item=”B2”><Qty value=”5”/></Compose>

</Item>

 

3.2.2 Produce element

Produce element defines a relation between processes and items, or a relation between operations and lots.  This element can show the quantity of the item or lot produced by the process or operation respectively, or how many items or lots are produced by the process or the operation respectively.

3.2.3 Consume element

Consume element defines a relation between processes and items, or a relation between operations and lots.  This element can show the quantity of the item or lot consumed by the process or operation respectively, or how many items or lots are consumed by the process or operation respectively. 

3.2.4 Assign element

Assign element defines a relation between processes and resources, or a relation between operations and tasks. This element can show the volume of capacity provided by the resource or task assigned for the process or operation respectively, or how many resources or tasks are used.

3.2.5 Relation element

Relation element can show that the parent element has a specific relation to other primitive elements.  This element can additionally define relational classes between primitive elements.  Examples include precedence relations and pegging relations.

A.  Object Class diagram

Figure A-1 shows the structure of primitive objects in this specification with a UML class diagram. Each object corresponds to each XML element. In this figure, arrows represent relative information between the source and destination objects. When an arrow has role names, it corresponds to an independent XML element in the specification. This figure doesn’t include all the information of XML schema but the partial information of the primitive elements.

B.  Cross reference of elements

Table B-1 shows the relations between elements. The row headers represent parent elements and the column headers represent child elements. Symbol * in the table means 0 or more than 0 element can be described.

 

Table B-1 Element and sub-element relations

 

 

 


The following table B-2 shows the correspondence between elements and attributes. The row headers show the element name, and the column headers show attribute the name. The characters in the table represent data types. The character in the table are used as follows:  “U” denotes identification character of element, “P” denotes an identification character of referencing elements, “S” denotes the character string, “D” denotes a decimal number, “N” denotes an integer number and “T” for date time.  Boldface means required information.
