“…The alternative next event request (NER) and flush queue request (FQR) are the basis of conservative eventdriven and optimistic protocols and could possibly form the basis of better performance. Indeed, other approaches such as the FAMAS backbone [4] may also yield better results. However, without the existence of the CSPE benchmark, it would be difficult to make an informed comparison as to which approach is best.…”

“…One of the outputs of the forum is the classification of some of the interoperability requirements of COTS-based distributed simulation on the basis of interoperability reference models [3]. These are as follows: There have been various attempts to interoperate models and the COTS simulation packages in which they have been developed [4][5][6][7][8][9][10]. Most of these approaches deal with the interoperability problem of transferring an entity, or similar representation of a temporary model state, between models and their CSPs.…”

A Comparison of CMB- and HLA-Based Approaches to Type I Interoperability Reference Model Problems for COTS-Based Distributed Simulation

Commercial-off-the-shelf (COTS) simulation packages (CSPs) are software used by many simulation modellers to build and experiment with models of various systems in domains such as manufacturing, health, logistics and commerce. COTS distributed simulation deals with the interoperation of CSPs and their models. Such interoperability has been classified into six interoperability reference models. As part of an ongoing standardisation effort, this paper introduces the COTS Simulation Package Emulator, a proposed benchmark that can be used to investigate Type I interoperability problems in COTS distributed simulation. To demonstrate its use, two approaches to this form of interoperability are discussed, an implementation of the CMB conservative algorithm, an example of a so-called "light" approach, and an implementation of the HLA TAR algorithm, an example of a so-called "heavy" approach. Results from experimentation over four federation topologies are presented and it is shown the HLA approach out performs the CMB approach in almost all cases. The paper concludes that the CSPE benchmark is a valid basis from which the most efficient approach to Type I interoperability problems for COTS distributed simulation can be discovered.

“…Full simulation involves lower costs; however, it may disregard some phenomena that are present in the real system, or it may contain additional factors that might influence the outcomes. Emulation and real-time control have the advantage in that they can be carried out in a cheaper way than full prototyping, they stay closer to reality, and they are, therefore, less time-consuming than full simulation (Verbraeck et al, 2000;Mueller, 2001;Boer et al, 2002).…”

Container terminals are struggling with a continuously increasing volume and increasing performance demands. As space is typically limited, terminals are searching for solutions to increase throughput capacity without expanding their physical footprint. Furthermore, they aim to increase their productivity on vessels in order to be able to handle bigger ships with larger call sizes in the same time frame. A terminal operating system (TOS) plays a major role in today's terminal operations, as it supports planning, scheduling and equipment control. Recently more and more tasks are performed by the TOS. These tasks need to be well-tuned to the operation (such as stowage planning, grounding decisions and equipment dispatching) in order to reduce cost and risk. In this paper, we present a meanwhile proven, safe and inexpensive approach to test and tweak the TOS and train operators on an emulated virtual terminal. This novel approach in the field of container terminals has been successfully applied during the previous 3 years at over 15 container terminals.

Nowadays container terminals are struggling with a continuously increasing volume. Therefore, they are searching for solutions to increase throughput capacity without expanding their physical footprint. Furthermore, they aim to increase their productivity on vessels in order to be able to handle bigger ships with larger call sizes in the same time frame. A terminal operating system (TOS) plays a major role in today's terminal operations as it supports planning, scheduling and equipment control. Recently more and more tasks are performed by the TOS -stowage planning, grounding decisions, equipment dispatchingand therefore, they need to be well-tuned to the operation, which remains a terminal specific characteristic. In this paper, an approach is presented to test and tweak the TOS and train operators on a virtual terminal. The implementation of this approach has been successfully applied during several TOS update or replacement projects for Rotterdam,
