SIMULATION MODEL DESIGN
仿真模型设计


ABSTRACT
摘要

In
this
state
of
the art
talk, we
will
present
a
structure for
defining
and
categorizing
simulation
model
designs.
In
the
past,
simulation
researchers
have
created
categories
for
discrete
event
simulation: event, process and activity; however, there are problems with this breakdown. First,
the major problem is that the taxonomy based on these three sub-types deals with only discrete
event
methods.
Discrete
time
methods
including
a
spatial
decomposition
of
a
physical
system(cellular automata, L-Systems) or a continuous model are not included. Second, the terms
“event,” process”

and “activity” create a division among classes
of simulation languages, rather
than
a
division
based
on
model
design.
The
term
“process,”
f
or
example,
is
really
a
level
of
abstraction higher than “event” and
is not
orthogonal
to “event.” The structure that we
present in
this
talk
is
more
comprehensive
and
provides
simulations
with
a
unified
framework
that
is
independent of the terms
discrete
and
continuous.

1 OVERVIEW
1
概况

Simulation is a tightly coupled and iterative three component process composed of 1)
model
design, 2) model execution
and
3)
execution analysis
as shown in Fig.
1
along with the relevant
sub-areas and book chapter numbers in a book which has just been published in the Fall of
1994
(Fish wick
1995).
The bold lines in Fig.
1
are to show our emphasis in the text:
model design
and
model execution.
The third area of
execution analysis
already has broad coverage in simulation
and is not covered in the book or this state of the art talk. Also, in this talk, we will cover model
design and not algorithms for model execution. Perhaps the hardest general problem in simulation
is determining the exact method that one should use to create a model. After all, where does one
begin?
Just
as
the discipline of software engineering has emerged to address this question for
software, in general, modelers also have a need to explore similar issues:
how dower engineer
models?
While there are many modeling techniques for simulation, we are often in a quandary as
to which model technique to use, and under what conditions we should use it. Our approach is
depicted in Fig.
2
along with the associated chapter references where each modeling method is
defined. For the talk, we will proceed to briefly discuss the model types. A more complete written
treatment is provided in Fish wick
(1995).

模型类型

There are five basic model types, and one complex
”kJ type which includes abstraction levels,
each composed of one of the basic types. All model types are now discussed.

Conceptual Models
(1)

概念模型

Conceptual
models
represent
the
first
phase
in
any
modeling
endeavor.
All
static
and
dynamic
knowledge about the physical system must be encoded in some form which allows specification of
interaction without necessarily specifying the dynamics in quantitative terms. Semantic networks
(Woods
1975)
present
one
way
of
encoding
conceptual
semantics;
however,
we
have
chosen
object-oriented
design
networks
(Booch
1991;
Rumbaugh,
Blaha,
Premerlani,
Frederick,
and
Lorenson 1991) which have more formal treatment. The ultimate conceptual model is one based
on database technology, such as an object-oriented database, capturing all facets of the physical
system.

Declarative Models
(2)

Declarative
型号

These models permit dynamics to be encoded as statetostate or event- to-event transitions. The idea
behind declarative modeling is to focus on the structure of state (or event) from one time period to
the next, while de-emphasizing functions or constraints which define the transition. Models such
as finite state automata (Hopcroft and Ullman 1979), Markov models, event graphs (Schruben
1983) and temporal logic models (Moszkowski 1986) fall into the declarative category.
Declarative models are state- based(FSAs), event-based (event graphs) or a hybrid (Petrinets
(Peterson 1981)).
