    Abstract
    This thesis studies about designed of sustainable chemical supply chains under un certainty in the life cycle inventory related to the network operation. Mathemati cally design formulated as bi-criterion stochastic mixed-integer nonlinear program that simultaneously account to maximize the net present value (NPV) and to mini mize the environment impact for probability level. Environment activities Measured through Eco-indicator 99, which incorporates the advancement made in Life Cycle Assessment (LCA). Stochastic model changed to be equivalent with deterministic by formulating probabilistic constraint that is required to calculate the environmen tal impact in the space of uncertain parameters. Then the result of deterministic bi-criterion MINLP is formulated as MINLP parametric, that is finished by iterat ing by decomposing it into two sub-problems finished by iterating. These solutions provide valuable perception about design problem and intended to guide the decision maker towards the applying sustainable alternative design.
     
    Tesis ini membahas desain rantai suplai bahan kimia yang berkelanjutan dengan adanya ketidakpastian persediaan yang terkait dengan jaringan. Desain matema tis dirumuskan sebagai stokastik campuran bi-kriteria program integer nonlinear yang secara bersamaan memaksimalkan net present value (NPV) dan meminimal kan dampak lingkungan untuk tingkat probabilitas tertentu. Kinerja lingkungan diukur melalui Eco-indikator 99, yang menyertakan kemajuan yang dibuat dalam Life Cycle Assessment (LCA). Model stokastik diubah menjadi setara determinis tik dengan merumuskan kendala probabilistik yang diperlukan untuk menghitung dampak lingkungan dalam ketidakpastian. Hasil deterministik MINLP bi-kriteria selanjutnya dirumuskan sebagai MINLP parametrik yang diselesaikan dengan menguraikan menjadi dua sub masalah yang diselesaikan dengan iterasi. Solusi ini memberikan wawasan berharga masalah desain dan dimaksudkan untuk mem bimbing pengambil keputusan terhadap penerapan desain alternatif berkelanjutan
