Integrated optimization of mixed-model assembly sequence planning and line balancing using Multi-objective Discrete Particle Swarm Optimization

Recently, interest in integrated assembly sequence planning (ASP) and assembly line balancing (ALB) began to pick up because of its numerous benefits, such as the larger search space that leads to better solution quality, reduced error rate in planning, and expedited product time-to-market. However, existing research is limited to the simple assembly problem that only runs one homogenous product. This paper therefore models and optimizes the integrated mixed-model ASP and ALB using Multi-objective Discrete Particle Swarm Optimization (MODPSO) concurrently. This is a new variant of the integrated assembly problem. The integrated mixed-model ASP and ALB is modeled using task-based joint precedence graph. In order to test the performance of MODPSO to optimize the integrated mixed-model ASP and ALB, an experiment using a set of 51 test problems with different difficulty levels was conducted. Besides that, MODPSO coefficient tuning was also conducted to identify the best setting so as to optimize the problem. The results from this experiment indicated that the MODPSO algorithm presents a significant improvement in term of solution quality toward Pareto optimal and demonstrates the ability to explore the extreme solutions in the mixed-model assembly optimization search space. The originality of this research is on the new variant of integrated ASP and ALB problem. This paper is the first published research to model and optimize the integrated ASP and ALB research for mixed-model assembly problem

Kepuasan Pasien Pengguna Kartu Jakarta Sehat di Unit Rawat Jalan Rumah Sakit

Peluncuran Kartu Jakarta Sehat (KJS) pada bulan November 2012 mengakibatkan jumlah kunjungan pasien yang melonjak drastis di fasilitas kesehatan, khususnya rumah sakit, baik itu rumah sakit pemerintah pusat, rumah sakit pemerintahdaerah maupun rumah sakit swasta yang berkomitmen dengan Pemerintah Daerah Jakarta. KJS memberikan kemudahan akses layanan kesehatan agar pasien dapat berobat secara gratis. Namun persoalan yang muncul kemudian adalah pasien harus mengantre lama di loket pendaftaran, ruang pemeriksaan, maupun ruang pengambilan obat. Penelitian ini bertujuan untuk mengetahui hubungan faktor sosial budaya, pribadi, dan psikologis dengan kepuasan pasien pengguna KJS pada 110 responden di Unit Rawat Jalan RSU UKI, dan telah dilaksanakan pada bulan Maret 2013. Rancangan penelitian yang digunakan adalah deskriptif kuantitatif dengan pendekatan potong lintang. Hasil penelitian menunjukkan kepuasan pasien KJS sebesar 40,9%. Akses ke rumah sakit, motivasi, informasi baik dan informasi tidak baik berhubungan signifikan dengan kepuasan pasien KJS, tetapi motivasi adalah hal yang paling dominan berhubungan. Selain itu, kepuasan pasien KJS juga berhubungan bermakna dengan pemanfaatan kembali layanan dan minat merekomendasikan layanan pada orang lain.Jakarta Health Card (JHC) was launched on November 2012, followed by sudden increase number of patient in any hospital accordingly.
