課程 6（共 9 門，Specialization Digital Manufacturing & Design Technology ）

Enterprises that seek to become proficient in advanced manufacturing must incorporate manufacturing management tools and integrate data throughout the supply chain to be successful. This course will make students aware of what a digitally connected enterprise is, as they learn about the operational complexity of enterprises, business process optimization and the concept of an integrated product-process-value chain. Students will become acquainted with the available tools, technologies and techniques for aggregation and integration of data throughout the manufacturing supply chain and entire product life-cycle. They will receive foundational knowledge to assist in efforts to facilitate design, planning, and production scheduling of goods and services by applying product life cycle data. Main concepts of this course will be delivered through lectures, readings, discussions and various videos. This is the sixth course in the Digital Manufacturing & Design Technology specialization that explores the many facets of manufacturing’s “Fourth Revolution,” aka Industry 4.0, and features a culminating project involving creation of a roadmap to achieve a self-established DMD-related professional goal.

Introduction to a Set of Supply Chain Management Tools & Integrated Capabilities

In this module, we will introduce the current enterprise management tools (such as ERP, MRP, and MES) that are often employed to integrate capabilities of various entities through the supply chain. We will provide a broad overview of these tools, and will review the capabilities of each of them.

In this module, we will introduce the Car Enterprise Management Tools such as ERP, MRP,

and MES, that are often employed to

integrate capabilities of various entities through the supply chain.

We will provide a broad overview of

these tours and we'll review the capabilities of each of them.

Upon completion of this module,

you will be able to;

distinguish activities related to scheduling, production planning,

and inventory control in a manufacturing system,

to state the features of manufacturing process management systems,

described the capabilities of enterprise resource planning systems.

Let's define three concepts: inventory,

scheduling, and production planning.

Inventories are the resources or manufactured products that a company hoards,

for example raw materials that the company has stored for future use.

The scheduling is the process of arranging, optimizing,

and allocating different resources to manufacturing activities.

Production planning refers to the planning of production activities by

proper resource allocation based on consumer demands and production capacity.

Production planning has four steps and basically

deals with determining how much and when to produce.

The first step is to identify

the required product mix and factory load with respect to the demand.

The second step is to allocate

the available current level of resources and match them with production load.

The third step is to schedule the actual workload activities in the factory,

and finally step four is to schedule and setup the delivery of the products.

Now that we are familiar with the concepts of inventory,

scheduling and production planning,

let's talk about Material Requirements Planning or MRP1 systems.

MRP1 is a software-based tool that matches production planning with

inventory control of a company in order to control and manage manufacturing processes.

MRP1 aims at optimizing the connection of supply and demand.

It ensures enough materials are available for production,

in order to meet demand.

If that is not possible,

it determines what to purchase and when.

In addition, it schedules production activities and ensures that the level of

inventory is maintained as low as possible to avoid inventory holding costs.

For each component of the product or assembly,

MRP1 seeks to establish required inventory levels.

The MRP1 system starts with establishing the total inventory required.

Then the sum of beginning inventory levels and current receipts is

deducted from the total inventory requirement to establish inventory needs.

Typically, a safety stock is added to mitigate contingencies.

MRP1 integrates data production schedules and

inventory levels to determine resource purchases and delivery schedules.

Production of large quantities of identical products

was something common in 1960's and 1970's,

when MRP1 first was released to the market.

These days the consumer plays a significant role in

production planning and influences many aspects of manufacturing systems.
