AL-Arz Company
From our humble begging in1950 , producing ice in order to cool water and store food
at the time when electricity didn’t exist , Al Arz company has evolved to be the leader
of frozen treats market in Palestine . Since its establishment by the late Mohammad
Anabtawi in Nablus – Palestine , AL- Arz grew in to a successful producer of high
quality extruded ice-cream products.
In 2007 , the company started its first step towards exporting, where Jordan was its first
station. That was after it acquired the Palestinian quality certificate .
Tow years later, the company acquired the global food safety certificate HACCP. This
achievement was a Palestinian industrial pride, since AL ARZ was the first company
that acquires this certificate among the ice cream and dairy manufactures in Palestine
and Jordan.
History of Al -Arz Company
Maintenance Any activity, such as tests, measurements, replacements, adjustments and
repairs, intended to restore or retain a functional in a specified state in
which the unit can perform its required function
Types of Maintenance
Preventive maintenance
Corrective maintenance
Maintenance Management System in AL-Arz Company
Sources of Data Collection
Data information was taken from Al-Arz company by this ways: By making frequent visits to the factory and observe the
process of maintenance. By the manager of Research and Development Department
(R&D).By help from maintenance manager (Mechanical engineer).
Flow Chart
Turning point for maintenance management system in AL-Arz Company
The turning point that occurred due to this project is to shift maintenance
management system in the factory from manually system to an integrated
computerized system using the program " Microsoft office Access " , which led to
saving time, effort and increase accuracy in the process of information storage and
retrieval speed . Plant need for Computerized Maintenance to demonstrates the
flow chart from start to finish or from the time of the failures until the system
return to work again, explaining the steps and tools and spare parts used and the
engineer in charge of maintenance process.
The turning point is to convert (MMS) to (CMMS)
Performance
Analysis
Types of failures analysis:This part talks about the types of failures (Mechanical, Electrical, general
maintenance services, and Structural).
Type of failure with frequency: This section shows the relation between each type of failure (Electrical,
Mechanical, Structural, and general maintenance services) and their
frequencies in general, and the relation between each type of failure with its
frequency.

Results of analysis:1-More failures in most time occur on Saturday because in Fridays there is no maintenance for the machines.
2-There are high differences of frequency from period to other because neglecting the documentation of all maintenance reports. 3-More failures are occur in packaging machine andالنفاشه""machine, because this two machine have the highest use in this company. 4-The highest frequency is in the period from (1\1\2010-30\4\2010) because this period are the beginning season (high production), and the machines work for long time in this period
Recommendation:
1 .Al -Arz company is highly advised the new model (CMMS) that can be easily managed by their managers and operators.
2 .To Convert manual system of maintenance to computerized system.
3 .It must be good documentations of maintenance report.
4 .It must be a good contact between Managers and employees.
