Unit 14: Simulation Languages (II)

GASP Notes

GASP IV is a FORTRAN-based simulation language which provides the framework for modeling
systems involving both continuous and discrete phenomena. A general ization of the definition
of “event” allows for time to be advanced in a next-event fashion while permit ting a step-wise
evaluation of system state variables described by difference or differential equations.
Subprograms are included in GASP IV to handle the details of state and event control (including
state- variable integration when necessary), information storage and retrieval, collection and
analysis of data on system performance, and generation of reports and plots. In this paper, the
GASP IV philosophy and modeling approach are described. Descriptions of the subpro grams
included in GASP IV and the required user- written subprograms are given. The types of applica
tions that have utilized GASP IV are listed. A com panion paper (beginning on p. 71) presents a
detailed example of the use of GASP IV for simulating a continuous reaction process involving
discrete startups and shutdowns.

Plant Simulation

In times of increasing cost and time pressures in production, along with ongoing globalization,
logistics has become a key factor in the success of a company. Money can be lost daily through
inefficient schedules, local instead of global optimization, inefficient resource allocation, and
poor productivity. The need to deliver just-in-time (JIT) / just-in-sequence (JIS), introduce Kanban,
plan and build new production lines and manage global production networks requires objective
decision criteria to help management evaluate and compare alternative approaches.
Tecnomatix Plant Simulation is a discrete event simulation tool that helps you to create digital
models of logistic systems (e.g., production), so that you can explore the systems’ characteristics
and optimize its performance. These digital models allow you to run experiments and what-if
scenarios without disturbing existing production systems or – when used in the planning process
– long before the real production systems are installed. Extensive analysis tools, such as bottleneck
analysis, statistics and charts let you evaluate different manufacturing scenarios. The results
provide you with the information needed to make fast, reliable decisions in the early stages of
production planning.
Using Plant Simulation, you can model and simulate production systems and their processes. In
addition, you can optimize material flow, resource utilization and logistics for all levels of plant
planning from global production facilities, through local plants, to specific lines.

Caselet Mobiles with Five-language user Menu

angalore-based United Telecoms has launched radiation certified WIWO mobiles
with user menu in five Indian languages — Tamil, Telugu, Kannada, Malayalam
Band Hindi.

“WIWO offers an ‘Indian solution’ by providing regional customers a choice of five Indian-
language menus; it has entered the market with the tagline ‘the new hello’; it is trendy,
available in eight models, loaded with innovative features and applications. It offers
differentiating features like noise-cancelling earplugs, dual battery, replaceable extra
speaker, WIWO user interface and animation, motion sensor and power torch. Additional
features like 3.5mm music jack in low-end phones, camera, bluetooth and expandable
memory make the WIWO phones an exciting buy for the discerning consumer,” Mr T.C.
Sudhir, Executive Director, Teleworld United said.
