A case study of time/cost analysis for aged-housing renovation using a pre-made BIM database structure

KSCE JOURNAL OF CIVIL ENGINEERING 2015年第4期19卷 841-852页

To successfully execute the construction project, many efforts have been made to apply 3D-based Building Information modeling (BIM). In practice, however, a data storage and retrieval system has yet to be developed because an extensive database structure is required in time/cost analysis for a particular project. This study is aimed to develop a generic BIM database structure and customize it for an aged-housing remodeling project. Throughout the Vicosoft's Constructor software, the pre-made BIM database structure has been developed. The case study has shown the efficacy and usability of BIM-based project management practice. The complete set of 378 pre-made recipe types have been defined with 55 methods and 47 resource items. The proposed BIM application process has been proven to be a useful tool for efficient project management by identifying work items and recognizing the relationships among activities. The advantages of using the pre-made BIM database to the time/cost analysis hare twofold: human error reduction and work efficiency. The limitations in and barriers against using the BIM database have also been discussed.

A State-Based Intention Driven Declarative process model

INTERNATIONAL JOURNAL OF INFORMATION SYSTEM modelING AND DESIGN 2013年第2期4卷 44-64页

Declarative process models support process flexibility, whose importance has been widely recognized, particularly for organizations that face frequent changes and variable stimuli from their environment. However, the currently dominant declarative approaches lack expressiveness for addressing the process context (namely, environment effects) and leading its execution towards a goal. This paper proposes a declarative model which addresses activities as well as states, external events, and goals. The model is based on the generic process model (GPM), extended by a notion of activity, which includes a state change aspect and an intentional aspect. The achievement of the intention of an activity may depend on events in the environment and is hence not certain. The paper provides a formalization of the model and describes an execution mechanism. It emphasizes the usefulness of specifying the intentional aspect of activities, by using it as a basis for semantic validation of the model at design time and for a planning module that can guide execution at runtime. These are illustrated by an example from the medical domain.

Information systems in general and process aware information systems in particular support the execution of business processes. This support is based on the assumption that the information system truly reflects the state of the domain where the process takes place. Based on this assumption, humans do not need to directly "sense" the state of affairs. Rather, decisions are made based on the state as reflected in the information system. This paper explores the situation where this assumption does not hold, namely, the situation of data inaccuracy. In particular, it formalizes data inaccuracy and addresses three questions: (a) how is data inaccuracy manifested in a process? (b) what are the expected results of data inaccuracy? (c) how can robustness to data inaccuracy be increased? The understanding gained with respect to these questions should form a basis for designing processes to be more robust, avoiding problems due to data inaccuracy.

Maintenance management process model for school buildings: An application of IDEF0 modelling methodology

引用

AUSTRALIAN JOURNAL OF CIVIL ENGINEERING 2010年第1期8卷 1-12页

作者： Akasah, Z. Amirudin, R. Alias, M. Univ Tun Hussein Onn Malaysia Fac Civil & Environm Engn Dept Bldg & Construct Engn Parit Raja Malaysia Univ Technol Malaysia Fac Architecture Johor Baharu Malaysia Univ Tun Hussein Onn Malaysia Fac Tech Educ Parit Raja Malaysia

The purpose of this study was to develop a process model for the maintenance management of school buildings. The proposed model was developed in a three-phase process: the information gathering phase using questionnaires, interviews and document analysis;the model development phase using the IDEF0 process modelling technique;and the experts' verification phase by three school maintenance experts. The potential usefulness of the model was tested on 61 school managers. The results of the survey indicated that the model has the potential to improve the existing corrective and reactive maintenance management practices towards preventive and proactive practices.

Learning business process models: A case study

5th International Conference on Business process Management

Learning how to improve business processes is an evolutionary process that must be managed as other business processes (BPs) are managed in modem organizations. The proposed model - the learning process model (LPM) suggests a closed-loop-model approach applied to a generic process model (GPM), which is a formal state-based and goal-based approach to process modeling. LPM strives to establish a learning process by (1) identifying goal and soft-goal states of the initial process model, (2) identifying exceptional states and incomplete state definitions at runtime, and (3) adapting automatically the process model according to the discovered states. Modifications provided by the learning process may be sufficient or may need to be complemented by non-automatic changes, when unacceptable business situations arise. The learning process also aims to adapt the current process model to possible technology, specific domain (e.g., clinical procedures at specific institutions), environmental requirements (e.g., regulations and policies), and process innovations. We demonstrate the application of LPM to a vaccination process.
