    Kajian ini memfokuskan kepada pemerhatian bagi pembolehubah-pembolehubah yang tidak boleh dikawal dalam Analisis Penyampulan Data (APD) untuk memodelkan kecekapan relatif industri pengagihan elektrik. Sepuluh kawasan pengagihan elektrik di Selangor dipilih dan digunakan untuk mengukur kecekapan relatif bagi kes di atas. Bedasarkan data bagi tahun 2002, model NCN dual digunakan dan mendapati lima daripada sepuluh kawasan pengagihan elektrik di Selangor adalah cekap. Satu set sasaran ditentukan bagi lima kawasan pengagihan yang tidak cekap. Berdsarkan keputusan ini, syarikat utiliti elektrik di Selangor dapat mewujudkan satu perancangan strategik bagi meningkatkan prestasinya, terutama dalam pengurusan kos.

    In this paper, we study analytical and numerical solutions of fuzzy differential equations based on the extension principle. For linear fuzzy differential equations, we state some results on the behaviour of the solutions and study their relationship with the generalised Hukuhara derivative. In order to approximate the solutions of linear and non-linear fuzzy differential equations, we propose a new fuzzification of the classical Euler method and then incorporate an unconstrained optimisation technique. This combination offers a powerful tool to tackle uncertainty in any numerical method. An efficient computational algorithm is also provided to guarantee the convexity of fuzzy solutions on the time domain. Several illustrative examples are given.
