INTRODUCTION study, Computerized Maintenance Management System (CMMS)

INTRODUCTION

            Maintenance
management becomes important to business performance and it is a complex
management process that has a significant impact on the overall results of
industrial. Maintenance management is the process of overseeing maintenance
resource so that the organization does not experience downtime from broken
equipment or waste money on inefficient maintenance procedures (Thompson, n.d.).  Maintenance activities include of the planning
of preventive maintenance, scheduling of maintenance activities, spare part
management and performance measurement and improvement. In this case study, Computerized
Maintenance Management System (CMMS) is adopted to support these functions. This
research discusses the CMMS in the term of their functions and application and
its limitation.

            Although
CMMS is offered in the market, the company prefers to develop their own system
in order to match the characteristic of the company. The new features that can
enhance the current system also discuss in this study which are Augmented
Reality (AR), Failure Mode and Effect Analysis (FMEA) and integration with
other company management systems. These features are discussed detail based on
the functions that have been defined. Through the analysis of these features,
the possible improvement can be determined.

 

 

CRITIQUE
AUTHOR

            From
the study, author concludes that the computerized maintenance management system
is an important tool for companies to support the maintenance management
activities. The author stated that computerized maintenance management system
(CMMS) is the information system that implements in companies to support
maintenance function like panning, scheduling and control the preventive
maintenance, management of spare parts and improve the maintenance performance.
From this article, we are agreed with the author’s point. This is because CMMS
provides important information to managers can help them to make the most
informed decisions possible.

A CMMS is a tool to support
maintenance strategy based on an information system and a set of functions that
process data to produce indicators to support maintenance activities (Lopes, et al., 2016). CMMS is not a
maintenance strategy but just only a tool to improve maintenance management. By
understanding the role of CMMS, which information the system must generate to
support the maintenance strategy can be defined. Implementation of CMMS allow
the company improve planning and scheduling of activities.

            Besides,
author also stated that the decomposition of the equipment by a tree structure
and associated failure modes, recording its cause and effects, will facilitate
failures analysis. We are also agreed with this statement. Augmented Reality
(AR) and Failure Mode and Effect Analysis (FMEA) are the systems that
contribute to facilitate the access to information in order to improve the
performance. AR includes both virtual reality and real-world elements. This
technology brings elements of the virtual world to the real world help to
enhance the current perception of reality. The realistic information is
important in maintenance management because information is the important
resources in supporting maintenance functions.

            Failure
Mode and Effect Analysis (FMEA) is a methodology used to identify the potential
failure mode and their resulting effects of the system. FMEA allow the company
define the failure mode of each equipment. The company can then evaluate the
cause and effects on the system of each failure mode. After that, the risks
associated with each failure mode can be reduced by the measurement. This
information of failure mode and effect help the managers understand the
capabilities of the system and take correction action to solve the failure. Cost
saving can be achieved because of the decreasing of failure rate.

 

KEY
LESSON

In this article, there are some
important key lesson that had been highlighted. First and foremost, application
and functions of computerized maintenance management system (CMMS) in
supporting maintenance activities. According to Lopes, et al., there are 5
functions of CMMS which are assets management, work order management,
preventive maintenance management, inventory control and report management.
These function help companies perform the maintenance activities efficiently
and effectively.

Assets management consists of
historical record for all equipment or assets. This include of
equipment-related data, such as service contract, safety procedure, and
inspection route. The maintenance histories of the equipment are also recorded
and list in a log book for references. If there is a problem occurs, the
technicians can refer the record in the list to see how the equipment is fixed
in the past and identify the cause of the problem. Next, work order management
allows the company to assign the work order to the maintenance technicians. The
detail of each individual work order is available for technicians. Technicians
easily access to their individual work and query relevant assets information. Preventive
maintenance management consists of planning, scheduling, and control of
activities. The availability of technicians, equipment, frequently and spare
part is considered in planning and scheduling the maintenance tasks. Besides,
inventory control allows the company to track the movement of inventory. The
location, cost information and availability of inventory can be tracked and
ensure the spare parts is available in the storeroom. The last function of CMMS
is report management. CMMS generates the easy-to-understand reports, so
managers can identify opportunities for improvement.

Besides that, information is the most
important resources in developing maintenance function. An information system
is crucial in maintenance management. According to Micheal Wienker, Ken
Henderson, and Jacques Volkerts, managing this process effectively without
computer-based support is almost impossible, but achieving successful
implementation of these systems requires a major change-management program over
many years. Information is a strategic resource in the organization.

Many companies prefer to develop
their own system although the CMMS is available in the market. This is because
CMMS does not perfectly match the characteristic of each company. The main
features defined in order to enhance the current system are Augmented Reality
(AR), Failure Mode and Effect Analysis (FMEA) and integration with other
company management systems. AR that consists of both virtual reality and
real-world elements facilitate the transmission of information. The realistic
information is transmitted to enable the technicians to take the right action.
FMEA is a technique defined the potential failure mode and their resulting
effects on the system. By the analysis of the failure mode, improvement of
maintenance plans can be achieved and reduce the failure rate. Lastly,
maintenance tasks should interact with other department management like
purchasing department, quality department and production department. They can
share information each other. Data is utilized for maintenance activities and
also other management functions.

In this case study, requirement
specification of proposed computerized maintenance system is based on four
major functions. For maintenance planning, the most appropriate maintenance
type need to be selected through the review of failure mode and another
measurement. The definition of intervention periods take into account some
factors which are reliability, availability and associated costs. In order to
identify the best maintenance type, Reliability Centered Maintenance (RCM) can
be adopted in the industries. Apart from maintenance planning, maintenance
scheduling also a function of maintenance management. An effective scheduling
must consist of both scheduled maintenance and unscheduled maintenance. The technician
will take action according to their own schedule. Decision support system (DSS)
can be implemented to obtain an adequate schedule.

In addition, performance measurement
and improvement. A balanced performance measurement can be achieved by
determining the economic indicators and human resources management. Analytical
hierarchy process (AHP) is a methodology that used to access equipment
criticality. AHP define critical equipment by prioritizing the most critical
factor. Lastly, spare part management consists of classification of the spare
part to allow the definition of adequate inventory management policy. Reliability
of equipment is an important factor that must take into account in spare part
management.

 

SUGGESTION/RECOMMENDATION

            After reviewing
the research, there are some recommendation can be implemented in order to
support the maintenance functions. Criticality analysis is a tool used to
evaluate how equipment failures impact organizational performance in order to
systematically rank plant assets for the purpose of work prioritization,
material classification, PM/PdM development and reliability improvement
initiatives (Vishnu & Regikumar, 2016). Criticality
analysis is performed based on risk. Based on the risk analysis and effect of
errors, the equipment will rank according to their importance for the business.
This methodology helps to prioritize the maintenance work and identify the most
critical equipment. Besides of ranking, the critical characteristic for each
equipment defined will provide valuable information to make the decision for
reducing risk action for equipment.

            Besides,
quality of maintenance engineers also important in repair and maintain electrical
and mechanical equipment in the industries. They involve in monitor and control
the device that helps in maintenance. They have the responsibility in
diagnosing the problem that occurs in the equipment and repair, test and made an
adjustment. Selection of maintenance engineers is important to make the
maintenance tasks can be performed perfectly. Maintenance engineers must be the
person who fully understands the maintenance system in the industries. They
have multi-skill in perform their work like technical skills, problem-solving
skills and team working skills. Work experience also crucial factors in maintenance
engineer selection.

 

CONCLUSION

            In the conclusion,
the computerized maintenance management system (CMMS) is an important tool to
support maintenance tasks. CMMS adopt in companies provide data to support
maintenance strategies and lead to improve maintenance performance by reducing the
failure rate and costs. Because of the rapid change of technology, the need for
new features is also rising. The companies prefer to develop their own computerized
maintenance system to fulfill the risen of need. Diagnose the current system
must be done in order to define new features of the new system. The requirement
of the proposed computerized maintenance system also needs to specify by
considering the maintenance functions. There are some opportunities for
improvement can be obtained by adding new features.
