Steel Fabrication Shop Visit Report Assumption Report

Introduction

This paper will present an assumption report on the steel fabrication shop after a visiting the premises of a suitable steel fabricator. For this purpose we will observe the fabrication equipment and fabrication processes in use the shop.

Overview of the business

After visiting the shop it has been observed that it is very nice steel fabrication shop that does both large and small structural steel work for construction jobs. Shop has been in business for about 5 years. Shop has contracts with some large customers, and does quality work. Shop is currently owner operated, and has high growth potential if a larger workforce were hired. Business has great equipment which is included in the sale. Business is located on a very high traffic 4 lane highway in a very highly visible location. (AbouRizk, 2000, 102-113) Business currently occupies an about 4,000 sq ft building with a great lease ($750 / month). Business is located in the Baton Rouge Metro area which is a great place to live and raise a family. Area has lots of affordable housing, many with large or acreage lots.

Fabrication Equipment

Various fabrication equipment, labor disciplines, and material handling systems involved in the steel fabrication process, and their interactions, were studied systematically to extract common modeling elements. The implemented SPS template for steel fabrication includes ten modeling elements: product, plant, shop, station, resource, storage, path, in port, out port, and a drawing tool. Sample graphic representations of modeling elements used by this template are demonstrated. A brief description of these elements is available in Table 1. (AbouRizk, 2000, 102-113)

Steel components defmed in the database system are introduced by the produci element to the facility model, and are further distributed to a shop element where the first operation can start, as specified by the process model. As a default, a steel component always travels to a station controller fmt. The station controller is a dummy station element that manages a group of stations performing the same operation. The station controller decides which component should be dispatched for processing fmt, and which station will be selected to perform this processing. The user can specify decision rules that control the behavior of the station controller. For example, the dispatching rules could be based on First-In First-Out (FIFO) or component priority, and the station selection rules could be random, alternative, or based on station priority,

Element

Description

Product

The product element imports steel components

defmed by the entity model in the

central database to the facility model. Then,

it releases steel components according to

dispatching schedules. The product element

also offers basic services, such as searching

stations, probing travel paths, and routing

1 for steel components.

Plant

This element represents a steel fabrication

facility. It is the parent of all shop elements.

Shop models are built as sub-models of the

plant element.

Shop

The shop element represents a fabrication

shop, the details of the shop are built as submodels
