"Penggunaan dispatching rule dalam menentukan urutan pengerjaan produk dalam flexible manufacturing system dapat memberikan solusi yang kurang baik apabila dispatching rule yang digunakan tidak sesuai. Pada tesis ini akan diperlihatkan perbandingan penggunaan beberapa dispatching rule baku dalam menentukan jadwal produksi, seperti First Come First Served (FCFS), Shortest Processing Time (SPT), Longest Processing Time (LPT), dan Earliest Due Date (EDD) serta sebuah usulan yang mempertimbangkan waktu terbuang untuk menunggu urutan pengerjaan produk pada mesin yang sama dalam waktu yang bersamaan dengan menggunakan alat bantu simulasi model. Pada tesis ini juga akan diciptakan model FMS dalam perangkat lunak, untuk kemudian disimulasikan menurut dispatching rules masing-masing, sehingga waktu penyelesaian masing-masing produk dan tardiness yang tercatat dalam hasil simulasi dapat dianalisa dan kemudian dibandingkan agar dapat dipilih untuk mendapatkan dispatching rules yang sesuai dan dapat memberikan kinerja yang paling baik. Perencanaan dispatching rule yang sesuai diharapkan dapat mempersingkat waktu penyelesaian tanpa melanggar tenggat waktu. Hasil yang didapatkan dalam penelitian ini menunjukkan bahwa dispatching rules yang sesuai merupakan kombinasi dispatching rule EDD dengan tetap mempertimbangkan waktu waktu terbuang untuk menunggu urutan pengerjaan produk pada mesin yang sama dalam waktu yang bersamaan melalui tenggat waktu minimum yang dimiliki masing-masing kombinasi urutan pengerjaan produk.

Dispatching rules, which commonly used in determining job execution sequences, should be well planned in order to avoid bad solution caused by the usage of improper dispatching rules. In this thesis, the comparison of several dispatching rules is made to establish a compact production schedule on an FMS using a model simulation, such as First Come First Served (FCFS), Shortest Processing Time (SPT), Longest Processing Time (LPT), Earliest Due Date (EDD) and a proposal to consider the wasted time caused in waiting execution on a same machine at a same time.

In this thesis, a model of FMS environment will be built on a software, and sequences which were produced on each dispatching rules, will be simulated based on the model created, for later the recorded value of completion time and tardiness of each product could be analyzed and compared further to gain a proper dispatching rule in giving the best performance. The proper dispatching rules planning will improve the completion time performance without violating the due dates.

The result from the case on this thesis will show that the proper dispatching rule is a combination between EDD and the proposal of considering the wasted waiting time with the concern of minimum due dates attribute owned by each product execution."

"PT XYZ merupakan sebuah perusahaan farmasi afiliasi Filipina yang menggunakan sistem flexible job shop dalam melakukan kegiatan produksi. PT XYZ memiliki rencana untuk menerapkan sistem produksi lean dalam aktivitasnya, Akan tetapi, tidak adanya metode penjadwalan produksi yang sistematis telah mengakibatkan munculnya banyak waste dalam lini produksi PT XYZ, seperti rendahnya utilisasi mesin, banyaknya mesin yang idle, adanya penumpukan work in process, dan seringnya terjadi perubahan rencana produksi, sehingga sulit bagi PT XYZ untuk menjadi perusahaan berbasis lean. Penelitian ini bertujuan untuk memperoleh sistem penjadwalan produksi yang tepat pada PT XYZ dengan berfokus pada upaya minimalisasi total waktu penyelesaian pekerjaan, sehingga berujung pada peningkatan efisiensi di PT XYZ. Dengan mempertimbangkan parameter job, mesin, operasi, waktu standar, dan bobot prioritas produk, disusunlah sebuah sistem penjadwalan dengan menggunakan aplikasi Visual Basic for Application. Solusi awal penjadwalan diperoleh dengan menggunakan salah satu aturan dispatching rule, yaitu weighted shortest processing time yang menghasilkan nilai makespan selama 67.080 menit. Selanjutnya, solusi kembali ditingkatkan dengan menggunakan metode algoritma tabu search, sehingga diperoleh nilai makespan minimal selama 52.485 menit. Solusi akhir penjadwalan yang dihasilkan mampu untuk meningkatkan efisiensi di PT XYZ sebesar 36.73%.

PT XYZ is a pharmaceutical company, which has an affiliation with Philippines, which uses flexible job shop system to its production activities. Right now, PT XYZ is going to implement lean production system to its daily. However, the absence of systematic production scheduling method has brought a lot of waste to PT XYZ production line, such as low machines utilization, many idle machines, many work in process, and frequent changes in its production plan, thus it becomes difficult to implement lean production system.

This research aims to obtain a proper production scheduling system for PT XYZ, which focus on minimizing makespan, so that leads to efficiency improvement in PT XYZ. By considering job, machines, operation, standard time, and product priority as its parameter, formulated a scheduling system using Visual Basic for Application.

Initial solution is obtained by using one of dispatching rule method, namely weighted shortest processing time, which results a 67.080 minutes of makespan. Subsequently, the solution was improved by using tabu search algorithm, so the makespan value would become 52.485 minutes. This solution is able to improve efficiency in PT XYZ by 36.73%."

"This Green Book offers the outstanding expertise of CIGRE professionals about Flexible AC Transmission Systems (FACTS) in one concise handbook. FACTS are used to enhance AC power networks, by providing fast control of power flows and AC voltage and AC phase angles. They can be used to defer the need for additional power lines, by controlling the power flow on lines to achieve maximum utilisation of the existing lines, and/or by improving the power quality, e.g. when large disturbing loads are connected to the network. This Green Book on FACTS provides comprehensive information about the use of Power Electronics for AC system control and for Power Quality Improvement in its over 1000 pages. This book has been written by experts in the field, who come from Transmission System Operators, Network owners, manufacturers, and consultants in this field. This Green Book on FACTS covers a large range of topics in its 6 sections, as follows:1. AC Systems Characteristics, AC network control using conventional means and AC network control using FACTS Controllers2. Technical Descriptions of all current FACTS controllers, power electronic Topologies for FACTS, SVCs, STATCOM, TCSC and the UPFC and its variations3. Application Examples of all FACTS controllers, which include a description of controllers using saturation of iron as well as examples of all current FACTS controllers4.
